SSL Certificates per domain

Postby shrf » Sun Jun 02, 2019 7:01 am

Hello ,

I installed SSL on the main domain and on secondary domains successfully and all working fine except the SMTPS on secondary domains.
If the main domain is mail.domian.com and the secondary domain is mail.domain2.com , and the user put mail.domains2.com in the outgoing SMTP , user receive SSL warnings.

I found a related bug for this issue RFE #50127 in KB 15103

Is there a work around for this issue ?

I have Zimbra version 8.8.11

Thanks

The domain cert you're using only works in nginx, not postfix (there are several threads on this).

If you want to "fix" this the easiest way is to use a single certificate based on a CSR that includes all the FQDN you want.
You might want to check the last Let'sEncrypt tool for ZCS, as it is the way it works.
