that you adapt the main domain name of an IP as the myhostname for POSTFIX or QMAIL.
Most of RBLS are checking the SMTP Banner and currently only the first domain name is being used. To reduce scamming or to prevent being blacklisted you should apply myhostname with the according domain name.

Thank you for your input! We will consider this functionality in upcoming releases if it will be popular.
Everyone, please continue voting for this feature if you consider it important.

Is this not implemented in Tools & Settings -> Mail Server Settings:
Outgoing mail mode
o Send from domain IP addresses
x Send from domain IP addresses and use domain names in SMTP greeting -

This is much needed.

some servers check the SPF of the HELO hostname and block the emails. we need to have this implemented to solve the problem.

It's time for this very big problem to be solved!
Why has it been sat out for a long time?
They get money for their work and then they don't get it to solve the problem for years.
I would like to have a Statemant on this matter!
Without Plesk this is possible with the postfix.
So they finally move. NOW -

I believe I've encountered this bug today.
Plesk instance is hosted on Azure.
We've configured the public IP with a DNS name and also configured reverse DNS.
However an outgoing mail from Plesk is getting rejected by Blueyonder (Virgin Media).
It says that the Plesk server is presenting the internal host DNS name in the SMTP message and it does not match the external DNS record.
I'm assuming this is the same problem and needs fixing urgently unless there is a workaround!? -

Totally agree with the last comment! The minimum is to have an answer, yes, no, maybe, when, next release?....! We are facing the same issue, banned anytime from many mail providers. My company is losing money during a "blacklisted" period. Please, answer and help us !
The option seems to be there in mail configuration but not cover cases of SMTP banner mismatch
Again, please, Help ! -

I find it totally unacceptable that a company THAT IS GETTING LICENCE REVENUE FROM ITS CLIENTS doesn't even take the time to acknowledge said clients when they are mentioning that their own clients are experiencing higher and higher number of issues because of Plesk issues - namely the PTR not matching the SMTP Banner when using a server for multiple clients!!!
Just shows the kind of care they have for their clients... I have read first about this issue being mentioned back in 2015 - https://talk.plesk.com/threads/plesk-12-smtp-banner-mismatch-critical-to-fix.331370/- we are now in September 2017 and Hotmail and Gmail are systematically blocking emails cos' of that mistmatch! No issue about IP rep, DMARC & Domain Key and SPF perfectly set! JUST THAT @@@ PTR / BANNER ISSUE!!!
PLEASE FIX - else next time I change server I'll switch for a company that DO CARE! -
