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?
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.
Since upgrading to Plesk 12 I am experiencing a strange bug:
When enabling the limitation of outgoing email messages, is not possible to RECEIVE emails to a account that is only redirecting the email messages (to a different account which also lies on the server).
I reproduced this behavior on two different servers from which one is a complete reinstall.
The maillog will then show the following error when receiving mails to a redirecting address:
Aug 1 04:04:34 xxxxxx plesk sendmail[16709]: handlers_stderr: DATA REPLY:554:5.7.0 The message could not be sent. You are not allowed to use sendmail utility.#012REJECT Aug 1 04:04:34 xxxxxx plesk sendmail[16709]: REJECT during call 'limit-out' handler
I can find very few information on this error message, but when disabling the limiting feature, everything works as expected.
my linksys switch comes with a web control panel under "qos" where i can control bandwidth there is Ingress Rate Limit and Egress Shaping Rate, what are they?
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.
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..
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
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.
I want to put custom values in /etc/postfix/main.cf, but I'm afraid plesk would overwrite them during upgrade. How can I safely add custom values to main.cf and preserve them duing plesk updates?
My environment: Parallels Plesk v12.0.18_build1200140606.15 os_Debian 7.0 64bits - postfix
In documentation about Server-wide-mail settings
In Plesk for Linux with the Postfix mail server, you can change the IP address used for sending mail. Also, if your server sends mail from domain IP addresses, you can specify which name will be used as a host name in SMTP greetings.
Choose from the three options:
◦Send from domain IP addresses. By default, mail from each domain is sent using the domain's IP address. The host name used in SMTP greeting is defined by the configuration of the mail server.
◦Send from domain IP addresses and use domain names in SMTP greeting. If selected, Plesk changes the mail server configuration so that the SMTP greeting will contain the name of the domain from which an email message is sent.
This option prevent the sender's IP address from being put into public black lists, such as the Spamhaus or OpenBL lists. This might happen if the mail server host name is used in SMTP greeting for the messages sent from domain IP addresses. Some recipient servers consider such messages as spam.
We recommend that you use this option if you host less than 100 domains. In case of a large number of domains, using this option significantly increases the load on the server.
◦Send from the specified IP address. You might want to use certain IPv4 and IPv6 addresses for all outgoing mail.
Sending all mail from the specified address might be useful, for example, if the IP address of the mail server was put into public black lists, such as the Spamhaus or OpenBL lists. If you select None, outgoing mail will not be sent.Click to expand...
Is it possible to get Plesk working with different bounce message templates? I'd like to make messages in my Polish language to make people know what the bounce problem is. How can I make plesk not to overwrite the main.cf and bounce directive ?
Ubuntu 14.04 with Plesk 12 (10 Domain License).Using this for mail only... multiple domains.Postfix and Dovecot installed. Trying to figure out how to do:
- SASL Auth (Dovecot) - TLS - want above two to be mandatory... no plain text auth and no unencrypted connections.
How do I achieve this with Plesk 12?I have found countless how-to's about doing this with Vanilla (non Plesk) installs with the same server software. However, Postfix main.cf and master.cf both appear to have specific Plesk modificatuons. Same thing for the related Dovecot conf files... also have Plesk specific modifications.
I see no way to enable the desired settings from the Plesk Panel. Can't achieve this within the Panel but also can't modify the conf files without potentially breaking some Plesk-specific functionality? My original hope in purchasing the Plesk license was to make administration of the mail server easier. Unfortunately, I'm struggling to do this now and may have already had this figured out had I not bothered with the Panel.
I am trying to secure my VPS and one thing noted in a recent scan was SSL v2 and v3 being supported for SMTP, POP3 and IMAP. So a check of ‘Disabling SSLv3 Support on Servers’ and the Postfix configuration settings suggest:
Examining both only the copy in /etc/postfix/ is configured and at the end of this file I can find all the Plesk settings, including some RBLs I’ve defined via the UI. Hence I know this is the working config as of the two, it’s the only one actually configured. Hence I add the required commands to the config:
... smtpd_tls_key_file = $smtpd_tls_cert_file smtpd_tls_security_level = may smtpd_use_tls = yes smtp_tls_security_level = may
[Code] ....
I then go to the Plesk Tools & Settings > Services Management and restart:
Now what I should get back is an error as the attempt to connect with SSLv2 should fail as it's an excluded protocol, but instead what I get back is the Plesk cert and a connection:
# openssl s_client -connect x.x.x.x:25 -starttls smtp -ssl2 CONNECTED(00000003) depth=0 C = US, ST = Virginia, L = Herndon, O = Parallels, OU = Parallels Panel, CN = Parallels Panel, emailAddress = info@parallels.com verify error:num=18:self signed certificate ...
Why? What do I need to do to have Postfix use the updated config and refuse an SSL2 connection?
I seem to have the same issue with Courier having made similar changes to the /etc/courier-imap/pop3d-ssl file:
