Plesk 11.x / Linux :: Qmail Delivery From Certain Senders Takes Up To 10 Hours

May 9, 2014

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.

Site IP Address Change Takes 48 Hours To Work

Apr 10, 2008

I changed my sites IP address via cpanel, but now it doesn't show up in a web broswer, I check out cpanel's website for information about this issue, and they posted this:

"It may take up to 48 hours for DNS servers to register the change and the site may not be associated with the new IP address during that time period."

is that true? change the sites IP address will take 48 hours to show up? I figured since it was all local IP stuff, it'll be a instant change and working instantly. since the name servers are all the same, ect.

anyone shed some light. I just wanted to know if I should give it a day to start working? or as of right now, I feel like I need to fix a cpanel error... but if its true, then everything is ok

Host Will Only Update Domain Name Server (DNS) In Batches, Takes Several Hours For A DNS Change, Normal?

Feb 10, 2009

Host will only update DNS in batches, takes several hours for a DNS change, is that normal?
Well today my mail stopped working and it turns out the A record for mail was deleted. How it got deleted I don't know.

I called my host and after speaking to 2 techs, they said that have added my request to a batch, and that would update in a few hours.

I said to him, batch? What can't you do it instantly?

He said thats not the way their DNS works and any DNS change would affect thousands of other sites they are hosting.

Does anyone know what kind of dns system these people could possibly have where they can not reload a single zone?

And by affected, I think he means the sites will go down for a minute or so, while it relaods every zone. Is this really the case, or are these people just idiots?

Plesk 12.x / Linux :: Deleted Backups Takes Long Time To Recalculate Free Space On Server

Jun 11, 2015

We had many backups stored on our Plesk 12 server about 51 GB in total.

After reducing the backups back to 10 GB by removing old backups through the Backup Manager.

The issue is that Health Monitor still reported that there was low diskspace displayed by color yellow. And it look Health Monitor over 16 minutes to change the alarm level from Yellow to Green

However the statistics at the specific subscription still present the Backup usage of 51 GB's whilest they are no longer there.

What can i do about this in order to speed up the synchronization?

Plesk 11.x / Linux :: How Qmail Is Configured

Jul 22, 2015

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?

Plesk 12.x / Linux :: Can't Switch From Qmail To Postfix

Jul 21, 2015

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?

Plesk 12.x / Linux :: Qmail Fails Due To Dh Key Length

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?

Plesk 11.x / Linux :: Slow SMTP Response From Qmail

Jun 16, 2015

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.

Plesk 11.x / Linux :: Qmail And SSL For Specific Mail Domain

May 27, 2015

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.

Plesk 11.x / Linux :: Qmail Email Messages Always In Queue

Nov 17, 2014

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.

Plesk 12.x / Linux :: Domains Not Showing - Qmail Does Not React To Panel

Sep 15, 2014

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?

Plesk 11.x / Linux :: SMTP Service (qmail) Stops Responding On Port 25

May 19, 2015

Since 15.05.2015 smtp experiencing problems.

Smtp service (qmail) stops responding on port 25:
# time telnet localhost 25
Trying 127.0.0.1...
quit
quit
Connected to localhost.localdomain (127.0.0.1).
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?

Plesk info:
OS Red Hat Enterprise Linux Server 5.9 (Tikanga)
Panel version 11.5.30 Update #50, last updated at May 18, 2015 05:21 PM
The system is up-to-date; last checked at May 17, 2015 10:56 PM

update: xinetd restart is definitely brings smtp alive, but it goes off after random period of time (5min ~ couple hours)

Plesk 11.x / Linux :: Qmail - Emails Not Delivered To Mailboxes / Stay In Queue

May 26, 2014

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?

What It Takes To Be An Unmanaged Linux Vps Admin

Aug 27, 2007

my previous experience has been shared, all operations are done by panels and ftp.

as some budget unmanaged vps is in my budget range (sub $10), i would really like to give it a go. but as i have no experience at all, i m not sure if i can manage it well. so i m here to ask, what do i need to know, what is the skill set to be an unmanage linux vps admin.

i am not a linux expert, but i've been using suse at work for java development, and trying out ubuntu at home. i know some basic skills like getting packages and install them. use pico to edit configurations files.

what i don't know is: what packages to get, and what config files to edit and how.

but as long as there's some tutorial for me to follow, i think i should be able to do it.

PHP Scripts And Nobody Senders

Apr 1, 2008

I have a user that wants to run a script that uses nobody as a sender. On the box it is disallowed to have nobody send emails in WHM, however, I have found that some are changing the setting in WHM to allow for nobody senders as long as phpsuexec is running, however, I'd like some feedback from the group.

1. Regardless of phpsuexec, is it more secure to require ALL php scripts to use smtp auth instead of any other workarounds for those scripts which use the webserver nobody as a sender?

2. How is everyone else handling this issue...

Plesk And Qmail :: Undelivered Email

Apr 21, 2009

I 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

Dec 1, 2008

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).....
