Plesk 11.x / Linux :: VPS With Multiple Domains - Mail Loops Back On Itself (postfix)
Nov 12, 2014
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.
If you do so, please include this problem report. You can delete your own text from the attached returned message.
The mail system
<stevew@maincompany.com>: mail for maincompany.com loops back to myself...
I have two domains as virtual hosts on same IP address.
I am getting certificate error for the second domain when I try to check email (using MS Outlook). I can't permanently "accept" certificate, it complains again and again. Certuficate I created and self signed for imap.domain1.com, but the second email server is imap.domain2.com, so it complains.
How do I set separate email certificates for two domains? Is it possible at all?

I run a virtual server (Ubuntu 12.04, Plesk 12, Postfix 2.9.6) using plesk to manage multiple domains. The server address is server.domain1.com. I use plesk to also manage domain1.com regarding all services, including DNS and mail.
What I just found is that postfix sometimes issues the following warning:
server postfix/trivial-rewrite[7397]: warning: do not list domain server.domain1.com in BOTH mydestination and virtual_alias_domains
The essential part of my main.cf is: myhostname = server.domain1.com mydestination = localhost.$mydomain, localhost.localdomain, localhost virtual_mailbox_domains = $virtual_mailbox_maps, hash:/var/spool/postfix/plesk/virtual_domains virtual_alias_maps = $virtual_maps, hash:/var/spool/postfix/plesk/virtual virtual_mailbox_maps = , hash:/var/spool/postfix/plesk/vmailbox virtual_transport = plesk_virtual
And /var/spool/postfix/plesk/virtual_domains contains amongst others:
domain1.com domain1.com/
I do not have any issues with receiving or sending e-mails right now, but would like to get rid of the error message however.
Could it be the problem that postfix automatically sets mydomain to $myhostname with skipping the first part (i.e., mydomain is implicitly set to domain1.com)? Should I manually set mydomain to server.domain1.com instead? Any other recommendations? Since mydomain seems to be used in multiple options [URL] ..., I wonder what I might destroy with changing this? As all mail services run without any further troubles at the moment, I don't want to break this...
As I assume that quite some people use a plesk-based server to manage the domain to which the server itself belongs to, I would assume that there should be a general fix/check to updated mydomain accordingly?
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
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?
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 am running a VPS through 123-REG, Plesk version 11.0.9 with CentOS 6.4
I host 3 websites of my own (with 14 mail accounts) 4 websites for clients (with 10 mail accounts) 7 websites for clients (with 0 mail accounts)
The problem I have had in the last 2 weeks is that the server has been compromised once again by spammers.
2 weeks ago we had another instance and the support was even worse than before, I decided that the best way forward after irradicating the problem and correcting the source, and in the interest of each of my clients I decided to asign each client with their own IP address in the vain hope that if one client account is compromised the others will not be affected, 123-REG agreed that this is a solid solution so I purchased 5 additional IP addresses for the clients I host mail accounts for, (all of the said addresses were blacklisted when I was given them!!!) the reverse DNS was not set up correctly, and couldn't be through their control panel and some didn't match the SMTP banners, then I found out through them that the mail was still sent out through the Primary IP address anyway so if one client gets blacklisted they all still do.
Now they tell me that I can in fact configure Plesk to use each IP address for each client exclusively and they sent me a link to a support article that doesn't actually tell me how to do it.
I can do the following so far:
Log into puTTY and use the command: nano /etc/postfix/master.cf
Find the "smtp" record referenced in the article [URL] 1.1.1.1- unix - n n - - smtp -o smtp_bind_address=1.1.1.1 -o smtp_bind_address6= -o smtp_address_preference=ipv4 2.2.2.2- unix - n n - - smtp -o smtp_bind_address=2.2.2.2 -o smtp_bind_address6= -o smtp_address_preference=ipv4
although mine looks like the one below: 1.1.1.1- unix - n n - - smtp -o smtp_bind_address=1.1.1.1 -o smtp_b$
Is there something missing from the entry I have?
Assuming that 1.1.1.1 = the relevant IP Address for the client do I need to create an entry for each of my IP addresses?
Do I need to do anything with SMTP banners? If so how do I do it, and what do I need to do?
The article also mentions the default settings being restored each time you reconfigure mail settings and to consider a scheduled task, does that mean each time I set up a new mail account or a new client as I assume that I will need to repeat these steps in that case anyway, mainly because they will have a unique IP address that needs to be set up.
In an environment where there is no webmail enabled for hosted sites and no sites have registered names (eg; they all belong in "our name space"), what is the affect of NAMED not running?
One affect that I have seen is with Site Scheduled Tasks that need URL resolutions. This appears to fail if Named is not running. All OTHER site content seems to work just fine. Apparently even in WordPress Multi-user/site situations.
I FULLY understand bind/named (and /etc/hosts, /etc/resolv.conf, /etc/nsswitch.conf), but it seems that it some cases, virtual hosted sites do not need Named (active) to function. This is NOT a case of incorrect DNS definitions created by Plesk for any hosted site.
SO - what is the "affect" of Named NOT running in a PLesk-12 Linux environment - not only for hosted sites but also the Plesk server itself?
Plesk 12.0.18 on CentOS 6.5 using Postfix...i have configured outgoing mail control to have a limit on a domain. I have removed all entries from the server wide white list.This setting - Allow scripts and users to use Sendmail is unchecked.However I can send any number of messages using PHP's mail() command from a PHP script on the domain.I see this in the maillog:Error during 'limit-out' handler...But the email is sent and no limit is applied.
sitea.com was pointing to /home/me/public_html/sitea
siteb.com was pointing to /home/me/public_html/siteb
On my new server, I have root permissions and used Plesk to create two domains sitea.com and siteb.com . Now plesk asks for a user to be created for each domain, so created usera and userb for sitea and siteb respectively.
Now as root on my server I created the dir /home/me/ and untarred the whole backup from old server to new server and I have dirs :
/home/me/public_html/sitea and /home/me/public_html/siteb
In apache configuration in file: httpd.include_sitea under dir /var/www/vhosts/sitea.com/conf/httpd.include
I changed the document root to /home/me/public_html/sitea
So I thought I am all set. But it does not work. When I try sitea.com in the browser it works but for all subdirs, for eg sitea.com/images it says Access denied.
This is because the dirs I created are owned by root.
So the owner of /home/me/public_html/sitea needs to be usera for this to work ?
Again for siteb to work I need to change the owner of /home/me/public_html/siteb to userb ?
This will be painful ? At least I should be able to change the owner of /home/me/public_html/ to one owner and ensure all sites under that work fine. How do I do that ?
I think the problem is clear by now. Its that I want all my sites to work off from .../public_html/ sub dirs.
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?
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] ....
