We are experiencing a slowdown on one of our servers running PLESK 8.2 . Has anyone noticed a problem with the latest qmail update provided by PLESK?
Our tech feels it is a faulty upgrade, and is looking into it.
Has anyone made the upgrade and noticed a problem? Our average load went from around 5 to 50.
i have a fedora core 4 server.. and i want to install a good Qmail email server to host some emails of diferent domains..
On searching i found that Qmail should be install with those associated programs/system for a better server :
Qmail itself
EZmlm and EZmlm-idx
Autoresponder
Vpopmail
VQadmin
maildrop
QmailAdmin
Courier-imap/imaps with Courierpassd
Squirrelmail web mail program ......
About four months ago I purchased a 1&1 VPS II for my site Crazy4Jigsaws.com. The site worked fine up until about a week ago. Now the site will become extremely slow (more than 2 minutes to load a page) for a period of 20 minutes to an hour randomly throughout the day. After this slow down period, the site will be extremely fast until the next slowdown occurs.
I contacted tech support several times and they claim that the site slow down is because my site is a php-mysql driven site and the slowdown is due to too many people visiting the site at once. My site gets only about 1,500 visitors a day and there are only simply sql queries being executed (ex: select a row out by its id key). They want me to buy a dedicated server but I can't imagine this is the problem. I have another site on a shared host that gets 10x as many visitors per day (another php-mysql driven site) and I've never had any problems with it.
So my question...am I really exceeding the VPS capacity? I've got 256 MB guaranteed RAM and I'm only using about 30% of it. If not, what could be causing the slow down? Tech support is "sure" this is the problem and has given up on my account. I mean if it can't handle my site, what type of site could it handle?
I bought a linux (cent os 4) vps with 128MB RAM on a 5Mbps connection. I am hosting just one proxy site using lighttpd and it uses about a Gigabyte of bandwidth per day. It gets between 500-900 uniques per day. The problem I am having is that the site is very slow even though it is not using much ram or cpu resources:

What could be the cause of the slowdown? Is it the 5mbps connection? How can I be sure?
Might be a weird question, but I have a test server setup with a single domain name and I am trying to figure out an easy way to get a bunch of emails to stay in the queue, anyone have an idea?
View 4 Replies View RelatedI have server running Plesk 8.6 with Qmail. Recently some users complain that when they send email out they received undelivered email from Qmail (plesk) with lots of unknown address. Users are concerned about that mail server is sending out mail that they did not send it to. I have attached one of the typical example that user got.
I have changed domain name and ip address for dummy address. I have no clue that the server automatically append those junk email address to the senders email or the client application did it without user's consent.
qMail inconsistent headers on Plesk
We are facing this problem on a Plesk (serverpsa v8.6.0_build86080910.19 os_CentOS 5)
The scenario is that on this server we have around 5 domains, one of them is the main domain that is also in the hostname.
On the main domain some custom social networking PHP script is running that sends out mails using SMTP authentication, now when welcome mail or invites or notification mails or any such mail are sent through the script, it includes other domains in the headers randomly:
Received: (qmail 15896 invoked from network); 24 Nov 2008 18:45:05 -0500
Received: from somedomain.com (HELO server.maindomain.com) (xyz.xyz.xyz.xyz).....
I am a new user of Plesk 11.5.30 struggling to understand how qmail is configured.
I intend to install ezmlm to work with qmail but the installation guide assumes that the qmail installation is set up per LWQ (Life with qmail - see URL....
For example the following are quotes from LWQ:All of qmail's system configuration files, with the exception of the .qmail files in ~alias, reside in /var/qmail/control.A series of configuration files resides under /var/qmail/users.
The qmail sendmail, which is normally in /var/qmail/bin/sendmail, usually replaces .None of these directories exist. So where are all these configuration entities?
I have issue with qmail server. I want to update ssl certificate and for this i have replaced older servercert.pem with new servercert.pem file in /var / qmail/ control/. and restart service of qmail using qmailctl restart.But after updating this certificate my web browser still showing older certificate details.
View 1 Replies View RelatedI have a Linux server running some reasonable setups:
Opteron 180, 4 GB RAM, running 8x 36gb 15k scsi with hardware raid 10 -- this is one of the servers from WebNX advertised here not long ago
Running CentOS 4(?), Apache2/MySql 4/PHP5.2, the normal stuff.
I have only one main site on the server, which runs a pretty old PostNuke CMS in Chinese (0.7.2.3 Phoenix) + PNphpBB2 + Gallery 1.5.7 (all integrated into PostNuke). This site is pretty light in "human" traffic, getting about 20K hits per day.
Now, the problem I have noticed with this site, is related to the many MP3 files stored in the Gallery albums. There are lots of HTTP requests to these files, most maybe from Chinese search engine bots (judging from IP), that slows the server to a crawl and even crashes Apache. This happens in the late hours here when it's day time in China. As a matter of fact I just did a reboot, and in 5 minutes there are more than 1000 HTTP requests to MP3 files resulting in a traffic of 2.1+ Gb. So within minutes, the server is brought to its knees again and I can't even get the "apache status" from CPanel now: "Unable to retrieve apache status".
The company that manages the server for me said there's no security problem here. We have installed an Apache extension to limit the number of simultaneous requests to media files to 1. However that doesn't seem to help.
I am unable to switch from qmail to postfix via the control panel. It opens a new window that just hangs and never loads. While waiting for it to load, I see these 2 processes running..
root 25108 0.1 0.0 133972 20604 ? S 21:58 0:00 /var/cache/parallels_installer/parallels_installer_CentOS_6_x86_64 --service-mode=components --enable-xml-output --ssl-cert /usr/local/psa/admin/conf/httpsd.pem --branch release,stable --web-interface --with-ssl --disable-browser
root 25109 0.0 0.0 104952 3032 ? S 21:58 0:00 /var/cache/parallels_installer/parallels_installer_CentOS_6_x86_64 --service-mode=components --enable-xml-output --ssl-cert /usr/local/psa/admin/conf/httpsd.pem --branch release,stable --web-interface --with-ssl --disable-browser
But after waiting 20 minutes, the browser never loaded and the two proceses remain. So I killed both processes and removed /tmp/psa-installer.lock and started again. The same thing happened.
Is there a way to fix this? If not, is there an easy way to switch MTAs from the command line?
I have been seeing these in my log and received complaints from customers not able to get their mail out. These messages just stay in the queue and go no where.
what they are successfully using as a tlsserverciphers and tlsclientciphers? Maybe it the dh key being too small. How can this be fixed on Qmail?
qmail: 1436646171.830486 delivery 6: deferral: TLS_connect_failed:_error:14082174:SSL_routines:SSL3_CHECK_CERT_AND_ALGORITHM:dh_key_too_small;_connected_to_170.49.86.238.
I have a Windows 2003 Server I use as a regular computer.
It would occasionally slow down to a crawl and programs become unresponsive. The hard drive light is usually on when this happens, and it usually lasts like a minute or two, then things are back to normal again.
Sometimes I'm lucky and get to open up task manager to try and see what's causing this. However every time the CPU load is low, and memory usage is normal.
How can I figure out what is causing this, or how to get rid of it?
Currently i'm migrating all my domains from ensim to Plesk.
I use for this the Plesk migration tool.
From the moment I change the nameservers, some mail will still be delivered (for a while) to the old ensim server and not the new plesk server.
How can I move or migrated mail from mqueue to the correspondening account under Qmail?
Because the ensim server is configured to be the final destination for mail . I cannot add extra MX records with a lower destination.
Or can i change easly the ensim server to be not the final destination)?
I want to add a new port for SMTP (1024) as a client's ISP block 25, 587 and 2525. I tried following this guide: [URL] ... but it doesn't work with Parallels Plesk Panel 11.5 ...
How to add an additional SMTP port to Qmail in Plesk 11.5?
We are seeing intermittent slow responses from SMTP on a RHEL6 server running Qmail on Plesk 11.5. The response is being measured from a remote Zabbix server.
The response time seems to be slow (>10s) for a period of 2-3 minutes and then returns to normal (<1s). All other services continue to be ok during the period of slowness.
The server_args line in /etc/xinetd.d/smtp_psa already contains "-Rt0" and all the DNS servers in /etc/resolv.conf are resolving properly.
From looking at the maillog file the server was receiving about 35 SMTP connections a minute at the time of the slowdown. We have the server configured to use 2 x RBL's.
I wonder if we are hitting a limit on the maximum amount of SMTP connections. The file /var/qmail/control/concurrencyincoming does not exist so, according to the Qmail manual, there shouldn't be a limit on the number of incoming SMTP connections.
Mail isn't leaving the queue, it's returning this error
Feb 12 23:12:01 XXXX postfix-local[64360]: System error .qmail: Permission denied
Feb 12 23:12:01 XXXX postfix-local[64360]: Wrong permissions for .qmail
All the files within /var/qmail/ are set to the user and group "popuser", and have the nessacery rwx permissions for the user/group.
The OS is CentOS.
Just got a strange problem on my plesk server. (11.0.9)
Qmail isn't working...
In Home>Tools & Settings>Services management SMTP "Server (QMail)" is stoppped.
When I try to start it, it say "Information: Please allow for some time for the service to start." but never starts...
In command line i try to restart it with "service qmail restart" and it says "OK" also if i run "service qmail status" it says "qmail-send (pid 2880) is running..."
but, it really doesn't work... queue is getting bigger and smtp isnt responding...!
I'm using Plesk 11.5.50 CentOS 6.5 64bit with Qmail. I have installed a SSL certificate on mail server "mail.company.tld" and is running successfully with smtp/pop3/imap4 daemon. Every user agent uses "mail.company.tld" for smtp/pop3/imap4. The qmail name is "mail.company.tld" (file me). The server has about 300 domains and 1000 accounts.
Now we want to add a new SSL certificate, called "mail.newcompany.tld", and use it only for certain domains. I would like to know if is possible to use the new SSL "mail.newcompany.tld" for a specific mail domain without using the old SSL "mail.company.tld" that isn't expired yet. From Plesk Panel I haven't found a section for using the SSL for a specific mail domain.
I have a server(godaddy) with plesk. It was all working well till 8 - 10 days ago. I didnt notice it one week later where I started receiving a lot of failed mail notices. Then on investigation, there were more then 50K spam mails in the mail queue and the mails that were supposed to be sent(registration, forgot password) were also held up in the queue. I found the source of the spam and fixed that.
Also I cleared the mail-queue. Now when I try to send out a test message, it still gets held up in the mail queue. But I can send a test mail to the same domain (info@mydomain.com). All new user registration mails are also held up and this is greatly affecting the site.
I need reinstall qmail after spam atack and follows the post.URL....It says:
rpm -Uvh --force psa-qmail
but my system return an error message..error: opening psa-qmail failed: it does not existe file or directory (error: la apertura de psa-qmail falló: No existe el fichero o el directorio)
rpm -q psa-qmail
return
psa-qmail-1.03-cos5.build1013120126.11
And my system is CentOS
I am running CentOS 5.10 (Final) with Plesk 11.5.30 Update #44 and since a few days have the strangest problem with incoming emails from certain hosts.
The email from known senders produces a relaylock message like:
/var/qmail/bin/relaylock [12345]: mail from 80.80.80.80:59595 (mail.hostname.com)
From what I was able to gather this is regular behaviour with plesk and qmail, indicating that the senders' mailserver has made contact.
Then nothing happens. For hours. 7-10 to be exact. Then the mail is being processed and delivered.
We installed a new VPS with Centos and Plesk 12.
Domains are simply not showing in the controlpanel. We can see the subscriptions but its empty under the button 'Domains'. Newly created sites as well as migrated sites do not show.
Before we created or migrated a site to the server we changed psa.conf HTTPD_VHOSTS_D /home/httpd/vhosts
This is a legacy from our old servers and never has been a problem. I suppose this is not related, but just thought I should mention it.
The second problem with this server is that when we toggle the mailservice in 'Services management' the button reacts but does not change the state of qmail. It just keeps running. What can be wrong with this fresh installation?
I have a PTR record and RDNS works for me but when i want sending email to this server : 62.152.169.25 error occurs and mail undelivery received.
qmail: 1403506829.587606 delivery 2978: failure: 62.152.169.25_does_not_like_recipient./Remote_host_said:_550_Invalid_RDNS_entry_for_144.76.245.38/Giving_up_on_62.152.169.25./
Since 15.05.2015 smtp experiencing problems.
Smtp service (qmail) stops responding on port 25:
# time telnet localhost 25

Escape character is '^]'.
quit
quit
Connection closed by foreign host.
real 4m10.629s
user 0m0.000s
sys 0m0.002s
After server restart or sometimes apache stop or ixnetd restart its responding for a some random time, and then again it stops to respond. Plesk panel show it as stopped but qmail itself running in memory, and does other its work, it just stops responding at port 25, or responds with a huge delay.
I've tried change it to postfix, reconfigured with mchk, repaired with repair.sh -r, disabled and uninstalled parallels antivirus, antispam, dnsbl, disabled firewall, disabled smtp lock. Checked apache, dns. Enabled submission port which works when 25 port doesnt, but i need working 25 port.
Nothing solves problem, its just stops responding after some random time. There is no errors on maillog.
I think this problem occured after recent plesk microupdate, because i didn't do anything to server configuration in last months.
This article says it might be dnsbl [URL] .... but it disabled(from plesk panel) on my server, maybe there is way to focefully kill any relation to dnsbl?

I'm having a hard time figuring why me emails are not delivered to mailboxes.
A bit of context:
OS: Ubuntu 12
Plesk pannel: 11.5
This server was supposed to be a new server (upgrade) from a previous who was working correctly (Also Linux with Plesk but both older versions).
After new server installed and websited up and running, I decided to create mailboxes and then copied all mailboxes (including emails and folders) to this new server.
First issue I got was i could not connect, until I figure out permissions were incorrect (for root after copy) and fixed it to be accessible by "popuser" (each user to access his mailbox).
Now i can connect, but new emails stay on qmail and can't be delivered to mailboxes.
Even after I have deleted the emalboxes and recreate them (now new emails are being delivered) all those emails in the queue can't be delivered.
I forced queue flush with "postqueue -f" but I get errors on the log:
(temporary failure. Command output: .qmail has prog delivery but has x bit set. (#4.7.0) 4.2.1 Message can not be delivered at this time )...
Which user should i give permissions (if that is the case) so tha both popuser (email user) and qmail/postfix can write on the mailboxes and deliver messages?
i got plesk 8.0, and trying to update with the updater to more recent versions.
updating fails.
I tried with incremental updates (8.0 > 8.1 > 8.2 etc.), but it never works.
I haven't really touched the configuration since I got the server.
this is the error I'm getting:

How can I update my apache and php to latest version in PLESK?
I need to install GD and Zend Optimizer too.
Whenever I try to update the Plesk key via webinterface I receive the following error:
Unable to connect to license server [URL] ....
cURL error description: Problem with the SSL CA cert (path? access rights?)(77)
Checking via command line shows that the SSL certificate of ka.parallels.com on port 5224 is expired in 2004 (!)
As it worked until today, why the SSL cert check fails now?
Is it possible through Plesk Linux version on the root servers to update?If not and you will update the Debian itself, you have to note something? What should you back up before everything to make Plesk is working again? Is a complete reinstallation is required?
