The problem is, can not send mail via SMTP using popular scripts Opencart, SMF, Osclass. The problem was lapping Plesk 11.5 via 587 port. That was timeout connection or authorization error with the correct settings. Mail may be sent, sometimes not. No longer working than working. At the same time when working with e-mail clients(example, The Bat) work fine. In Plesk 12 same problem. Port 465 - e-mail clients(example, The Bat) work fine. But can not send mail via SMTP using popular scripts Opencart, SMF, Osclass. When using Cpanel with Exim - all work perfect. But the Plesk e-mail with Postfix - constant problems.
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 have been trying to determine if I should use Postfix or Exim for our new SMTP gateway. My biggest obstacle is in trying to determine if Postfix can handle the processing as efficiently as Exim.
Basically we have hundreds of domains that will have email going through the gateway. I need to know if Postfix can be configured to perform different actions based on the recipient domain (i.e. block receipt of message or add a header and deliver). It looks like this functionality is handled by using a 3rd party tool like "amavisd".
The problem is that it looks like I have to wait for the DATA to be received before I can send the mail to the filtering tool rather than just waiting until the last RCPT command. It is also unclear as to whether the message will be denied during delivery with a 550 error being returned or whether the message is accepted and a postmaster message is sent. Obviously I would prefer the 550 error.
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.
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: connect from unknown[XX.XX.XX.XX] Aug 15 13:09:32 2d4 postfix/smtpd: E9AF61C58851: client=unknown[XX.XX.XX.XX], sasl_method=PLAIN, sasl_username=XX@XXX.XX Aug 15 13:09:32 2d4 greylisting filter: Starting greylisting filter... Aug 15 13:09:32 2d4 /usr/lib/plesk-9.0/psa-pc-remote: handlers_stderr: SKIP
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?
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] ....
This message is an automatic response from Port25's authentication verifier service at verifier.port25.com. The service allows email senders to perform a simple check of various sender authentication mechanisms. It is provided free of charge, in the hope that it is useful to the email community.
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.
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
I then go to the Plesk Tools & Settings > Services Management and restart:
