    Hello. 

    Does is possible to send a different sender hostname fo each domain that is hosted on a server?

    For example the domain domain.com send the SMTP hostname as mail.domain.com and example.com send as mail.example.com and not use a general hostname for example: mail.server.com

    Thanks in advance for all your help!

    Hello Dennis Molina Arguedas

    Please, check the section "Send from domain IP addresses and use domain names in SMTP greeting" in the article https://support.plesk.com/hc/en-us/articles/213905445

    Thanks Ivan.

     

    I'll check it. 

    Thanks for your reply! 

    However I used a main server name as SMTP name server in order to send all the emails with this sign, with the PTR pointing to the main record. 

     

    Best Regards.

    Hello, is this fix persistent or it will be wiped out by the first Plesk micro-update? Main.cf file seems to be overwritten pretty often. Thanks.

    Thanks Kuzma Ivanov,

    Your answer solved my problem with MXTOOLBOX regarding the SMTP Banner check.

    Regards

    Hello Riccardo Di Roberto

    It depends on the changes in a particular update. Indeed, there's a possibility that some updates will wipe manual changes. You may use 3rd-party software to automatically restore changes in main.cf.
