Question OpenSSL error in postfix log

[abanico]

Server operating system version

Almalinux 9.7

Plesk version and microupdate number

Plesk Obsidian 18.0.74 #3

Hello everyone,

On one of our servers with Plesk, which has Almalinux 9.7 installed (not an update, a clean installation), the following appears in the postfix log:

postfix/smtpd [31867]

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

The mail server seems to be working fine, but this line appears in the log continuously. I've looked in the forum and the closest thing I can find is to update postfix from the OS vendor repositories. Is this correct? Will I break anything? Do I do this using dnf update openssl\*?

Thanks a lot in advance!

It's an warning, not an error. You can safely ignore it, as it does not impact functionality.
