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)
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.
I'm using a 1blu.de vServer. On my VPS is Plesk 11.5 with centOS 6 installed. I created my Webspace [URL] .... and removed the Mail Services and activated the MSMTP plugin because I'm using the webserver from the hoster 1blu.de.
I activated the Firewall with the "allow any connection" rule.
In Plesk Tools & Settings > External SMTP Server I filled in the server informations smtp.1blu.de password & username. I checked all three boxes -> SMTP needs auth, allow user scripts ...
I installed Wordpress 3.9.2 with a Theme that uses PHP Mail function. The contact form is not sending any messages out. So I tried other php mail scripts but it doesn't work.
I am using Qmail for most of my email accounts which is taking up a lot of my Singapore bandwidth which is extremely expensive. Anyway to configure such that POP goes to my Singapore servers, while I setup a pair of servers in USA for my SMTP needs?
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.
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 (firstname.lastname@example.org). All new user registration mails are also held up and this is greatly affecting the site.
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've just moved over to a VPS package with startlogic and am running into a problem with having mail sent from my new server. Basically, mail is backing up in the mail queue and is failing to be sent, but then after a long time (a few days) it, or at least some of it, will suddenly be sent successfully for no apparent reason.
In the meantime the mail is backing up in the mail queue. Looking at the qmail logs I'm seeing lots of "Sorry,_I_wasn't_able_to_establish_an_SMTP_connection" type of errors, and occasional "Sorry,_I_couldn't_find_any_host_named_localhost.localdomain" errors (though the SMTP ones are far more common place).
I've gone through the plesk/virtuozzo mail server options and they seem fine, and it does send some mail through, just very sporadically and up to about 5 days late.
I am using Plesk Panel 11.0.9 (latest updates applied) on CentOS 6.4. at Strato. Unfortunately I can not send email from outside of the server (thunderbird). As I am not familiar wwith mail server configuration at all I would expect that plesk panel does that for me (right?)
* I can send emails via web mail. * I can receive emails in thunderbird, but sending runs into a timeout. * The plesk firewall configuration does have a rule for smtp (but I don't see for which port), so I would expect it is not a firewall issue * I would like to send with some security (starttls and encrypted password), but sending does currently also not work with any combination of (non-)security setting.
My domain has been migrated from another provider, I added it myself via Plesk panel later. The only mail-related change I did without plesk panel was to copy the mailboxes from my old server to /var/qmail/mailnames. But this should not effect sending email...
I am having trouble with setting up an email account to set up the email I go to Mail > Create Email Address > and enter email address (email@example.com) and check the "access to control panel" and create a password and also check "mailbox" .
But in the email client, when I go to use SMTP and I enter the following info:
- SMTP Server: example.com - username: firstname.lastname@example.org - password: password I created above - port 25 - user TLS
I get this error: Your other email provider is responding too slowly. Please try again later, or contact the administrator of your other domain for further information.
