Resolved OpenSSL and Postfix (run-time library vs. compile-time header)

[OverWolf]

Server operating system version

Almalinux 9.7

Plesk version and microupdate number

18.0.73 #4

Hi,
after I update to Almalinux 9.7 I have this warning :

postfix/smtpd Mail system

warning: run-time library vs. compile-time header version mismatch: OpenSSL 3.5.0 may not be compatible with OpenSSL 3.2.0

I have done some test and it seems doesn't affect the use of mail, but I would like to know if Plesk is working to resolve this situation or not.

Thank you

Hello,

On AlmaLinux 9, Plesk uses postfix from OS vendor repositories. Try to update your OS - it seems you have installed postfix from AlmaLinux 9.6 and openssl from 9.7 (it was updated from 3.2 to 3.5 in AlmaLinux 9.7)

Hi mizar,
this warning appeared after I've updated Almalinux from 9.6 to 9.7, so my OS is updated.
I've tried to check if there is other packages update but nothing.

After several searches I have found an answer about this problem that put this thread "as resolved":

libraries that follow a SemVer process (including OpenSSL >= 3.0), such an update is expected to be backward-compatible, so applications aren't usually rebuilt.
