Postfix SSL: Incoming email for multiples domains

Hello Team,

I have read multiple post about postfix to copy ssl for domain, but in my version I do not have any such function where I can copy ssl for the domains email postfix. The only options I have is Set as Default Services Certificate

I have virtual servers namely domainA(dot)com, domainB(dot)com and DomainC(dot)com, here when I set SSL of DomainB.com as default for Postfix then domainA and DomainC face problem in incoming email. In logs it cannot authenticate the certificate which is true.

How can I set certificates per domain for postfix ? Please suggest…

Regards,

I found steps to follow to resolve this issue on old setup, I tried it and still it did not make any changes.

How can I get the Copy to Postfix function?

Thanks.

I think the problem is in cached Postfix version by Webmin. It could be fixed by clicking force-refresh system information button in the dashboard, e.g.:

Hi Ilia,

Thank you for the quick response.

I tried this and still I am not able to see Copy Certificate to Postfix Button In Setup SSL Certificate

Though All 3 domains have working incoming emails at the moment but only 1 SSL Certificate is set as default.

Thanks.

What is the actual Postfix version currently installed on your CentOS 7 server?

postconf -d mail_version
mail_version = 3.8.4

It looks that you manually upgraded Postfix to the latest version on your CentOS 7 system, right?

If so, can you show the screenshot of the Servers ⇾ Postfix Mail Server page? I wonder how Webmin sees your Postfix version.

Anyway, deleting Webmin cached Postfix version file, i.e. /etc/webmin/postfix/version manually should solve your initial problem!

We will delete this file automatically, as part of force-system information refresh in the dashboard.

Awesome.

I see now.

Thanks a lot.
