Starting on October 19, 2021, we will enable single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
To be prepared for this change and to avoid the need to register during your next ticket submission after the change, we encourage you to create an account here before October 19 using the same email address as your current Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account. You will continue to use ZenDesk authentication until we switch over to single-sign-on on October 19th.

    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.

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

    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.

    What else do I have to change after this? I have existing mail accounts, did your proposed changes. But after that I could not receive mails and senders got the reply, that user "info" (my mail account) does not exist. It seems that plesk maps accounts with the hostname.

     

    thanks for your help in advance
