Plesk 12.x / Linux :: Postfix Relay - Connection Time Out On Forwarded Mail
Dec 1, 2014
My hosting provider recently (and without any warning) decided to block outgoing connections to port 25. What this means is for any client/domain/email address that has a forwarder setup, the mail will never reach its destination because the connection to the other server always times out. The error logs look like this:
postfix/smtp[8414]: connect to ASPMX2.GOOGLEMAIL.COM[74.125.131.26]:25: Connection timed out
postfix/smtp[8421]: connect to aspmx2.googlemail.com[74.125.131.26]:25: Connection timed out
postfix/smtp[8425]: connect to aspmx3.googlemail.com[64.233.186.26]:25: Connection timed out
postfix/smtp[8423]: connect to aspmx4.googlemail.com[64.233.166.26]:25: Connection timed out
I haven't been able to find a way to force relay to 465. Or maybe I shouldn't have relay on at all and do this another way?
I'm using Postfix 2.7.1 on Debian 6 with Plesk 11.0.9.
Currently the text of a bounce mail shows:
This is the mail system at host example.org.
Your message could not be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message.
The mail system
<_plesk_bounce_example.org@localhost.localdomain> (expanded from <ttt@example.org>): This address no longer accepts mail.
And I'd like to get rid of address <_plesk_bounce_example.org@localhost.localdomain>.
I added the bouce file template to Postfix's config by:
I m trying to get the feature "Outgoing Mail from Exclusive IP Addresses" working, as with an updated Postfix configuration the menu entry for this functions does not appear anymore.
Maybe i am missing something in my configuration that tells Plesk to not show it anymore.
Plesk 12 - fresh installation on Debian Wheezy.
We only changed main.cfnd here is the configuration file (please note that the formatting was a bit corrupted by the plesk panel ):
Code: alias_database= hash:/etc/aliases alias_maps= hash:/etc/aliases, hash:/var/spool/postfix/plesk/aliases append_dot_mydomain= no biff= no disable_vrfy_command = yes header_checks= regexp:/etc/postfix/header_checks mailbox_size_limit= 0
The VPS has 16 domains running on it, all with different web addresses and their own email accounts etc.
It's a Linux server and is running postfix for the mail. The main website on this domain has the mail service disabled because we have an exchange service on our own server here in the building where we work. Now when anyone on any of our domains on the VPS try to email us at 'maincompany.com' they get the following error message:
This is the mail system at host <vps address>.
Your message could not be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.

The mail system
<stevew@maincompany.com>: mail for maincompany.com loops back to myself...
My issue started ince a couple of months seemed to increase with update to Plesk 12.0 (though I can't guarantee it).I am using Centos 6.5, all updated. What happens is that postfix usage starts to increase without any apparent reason (during week-ends for example). Then postfix is not responding anymore.
I've been trying to set up Postfix to send email for the past few days. I've managed to get it to ask for a username and password, in order to try and send mail to an external domain
I can receive email fine on the server, but I can't send email out
I would like each of my clients who have a dedicated IP address and an SSL certificate to be able to use their own domain name (and own certificate) when sending mail on ports 465 or 587. I have managed to change the default certificate used by Postfix to my own server's certificate, but I want users to use their OWN IP address and SSL certificate when sending, so this is not an option.
I have been able to update Dovecot to use a specific certificate for each IP address, but I can't seem to update Postfix. I was trying to follow these instructions but my postfix master.cf was quite different than the poster's file and I didn't succeed: [URL] ....
I know many people will simply say "it can't be done" or "just get the users to use the shared IP address", but I know there must be some workaround to make this work, even if it means manually updating the config file after every Plesk update. I'm even prepared (if possible) to have Plesk abandon management of Postfix and have me manage it manually, if that's even an option.
Each migration in the last years I'm running into this bug that Postfix wants to run on port 587 even though this is turned OFF in the Plesk Panel.
Sometimes it does this after some update.
Because another process is running on port 587 this means that postfix does not start and I have some downtime until I "repair" this.
"Repairing" means going into Plesk panel and turning ON SMTP-Auth.... Wait a moment for it to apply and then turning it OFF again....
This unwanted behaviour can be easily reproduced by having this option turned off in the Plesk panel and then running /usr/local/psa/admin/sbin/mchk --without-spam
This will end up in a non-running postfix if another process is already running on port 587.
This shouldn't be happening. Especially because I reported this behaviour years ago..
on a fresh debian 7 64bit openvz system we actually have a problem with the new plesk 12 feature of limiting outgoing mails.We migrated about 25 systems to plesk, this is the first that makes problems.If limiting outgoing mails is activated (i double-checked all possible checkboxes in plesk) a fresh mailbox gives us the following error while trying to send via smtp:
Aug 15 13:09:32 2d4 postfix/smtpd[8645]: connect from unknown[XX.XX.XX.XX] Aug 15 13:09:32 2d4 postfix/smtpd[8645]: E9AF61C58851: client=unknown[XX.XX.XX.XX], sasl_method=PLAIN, sasl_username=XX@XXX.XX Aug 15 13:09:32 2d4 greylisting filter[8651]: Starting greylisting filter... Aug 15 13:09:32 2d4 /usr/lib/plesk-9.0/psa-pc-remote[8611]: handlers_stderr: SKIP
[code]....
After deactivating the feature all mail is sent without any problems. We use postfix + dovecot.
There are several big domains that frequently defer accepting mail from us causing long delays or rejections. Google, AOL, and Yahoo are examples. I'm considering trying the suggestions found in this online posting regarding rate limiting the sending of messages to those domains. In the below URL, please see the section titled "Different policies for different domains"...URL....
Would these changes be safe to make on a CentOS 6.4 server running Plesk 11.0.9 with Postfix 2.8.4? Would any special modifications for Plesk be necessary?
At this moment, all mail (no matter what domain) goes out straight to its destination. We want to send the mail trough a antispam firewall before it enters the internet.
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..
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 just upgraded my Plesk 11.5 on Plesk version: 12.0.18 Update #9 , and after the upgrade the Postfix stop working. And forwarding, receiving is not working at all and I am getting message bellow.
after reinstalling the mta / postfix / smtp (because I couldn't send mails) my plesk is crashed.
I wanted to log in as admin but it doesn't accept my PW. Now with root and then it wants me to accept the license.
Now I copy all my /var/www/vhosts/ maybe when I do the setup steps in plesk it will overwrite all my website content... I hope not all plesk settings are away.
Why I pay every month money for a license? The trouble and work I have with Plesk..
I know they're just self signed certs on the postfix mail servers used in PPA, but how can I renew them, customer was cautious about it once they saw it had expired.
I have found this: [URL] .... and was wondering is this the correct procedure to update the SSL cert?
We are using Plesk 11.5 with postfix MTA. Spamassassin is working fine for incoming mails and leaves outbound mails unchecked - as it should.
Now there is one of my domains whose mails are relayed to another server (using postfix transport tab; mail support for this domain is disabled in plesk). For the moment, these mails arrive without beeing checked and marked by spamassassin. How could I change this? I have tried to register an additional mail-handler like
If there is a direct way to enable spam-control for relay domains, Otherwise I could still access spamassassin via postfix' config-files, but how to use two different implementation of spamassassin at the same time.
I am currently using a VPSland windows 2003 vps, and noticed that on IRC, (via mIRC), i can't really connect to irc ports such as 6667, etc, but i can connect through other uncommon ports like 8080, or BNC ports. Does anybody know how to enable those irc ports on the windows vps?
My server is Plesk 12 with Postfix and Courier IMAP i am also using Thunderbird as mail client...
My question is when i create a folder from my mail client or webmail they just appear as sub folders of my inbox which is not what i want, i want root level folders not to be under inbox... When i searched for this i found [URL] ....
Is this still the case? Is there anything i can do to have root level folders?
I have a hard problem with my VPS. I have postfix as mail server on plesk 12 under ubuntu 12.
I dont know why the outgoing mails of all my domains in my servers are getting spam in servers like gmail, yahoo, hotmail...
I'm using mxtoolbox to fix errors and warnings and finally fixed all of them, but my mails are still outgoing to spam.
In mxtoolbox actually I have no mail server errors / warning, u can see it with, for example, this one of my domains: [URL] ....

I have a brandnew server with CENTOS 6.5 Final with Plesk 12.
For some reason unknown i'm not able to configure Postfix as smtp server and accept plain text autentication. It only accept TLS autentication both on port 25 or 587. If i install Qmail everything works without any problem.
Mail isn't leaving the queue, it's returning this error
