The mail server is located on the same host. For that reason it has the same name as the host. The hostname is configured in Tools & Settings > General Settings > Server Settings > Full hostname. If you wish to also address the host with a "mail" subdomain (e.g. because you need an SSL...

Hi! I need to add some kind of disclaimer in html to every email address from one domain. I found alterMIME which looks fine. But I have a question: is it safe to modify /etc/postfix/master.cf and add files to /etc/postfix/ ? Or how to do it without worrying that some Plesk updates will reset...

Do you see an easy DNS-based fix to have multiple domains (each dedicated IP) to match that static smtp banner? PS: I don't want to end up in overwritten customization by Plesk Update ... since Plesk doesn't manage the hostname in postfix for different mail-servers.

The PTR record exists it resolves to my hostname as it is shown in TOOLS & SETTINGS > SERVER SETTINGS >FULL HOSTNAME After some checks I found that: 1. there were 2 domains that were transferred from another server and in DNS zone had: a. the MX record referencing the old server...

By default, Postfix will show the hostname of the server in the SMTP banner. In most cases that's perfectly fine and will not cause any problems (despite mxtoolbox complaining about it), as long as the hostname in the SMTP banner can be resolved. So in my opinion you can ignore that. Plesk does...

Ok thank you for that information. So in general I should be fine? Don't want to go through the trouble of contacting every single provider because they put the domain on a blacklist because of a wrong SMTP Banner.

Well, SPF & DKIM were already added. All I did was to configure the correct domain name in Postfix settings as defined here: How to change the hostname and SMTP banner in Postfix on a Plesk server

My SMTP banner is: 220 mydomain.ca ESMTP Postfix Is the suggestion really to change the whole server hostname to mail.mydomain.ca ? Wouldn't the hostname applies to more than just the mail server ?
