We're currently seeing below in our logs
postfix/smtpd[827059]: warning: TLS library problem: error:0A000126:SSL routines::unexpected eof while reading:ssl/record/rec_layer_s3.c:336:

This was fixed in v3.7.4 and AL2023 has v3.7.2

It might be worth going up to the latest v3.7 - v3.7.12 to get the stability fixes and security updates though.

I got this message in the logfiles
May 18 11:42:32 ip-XXXX.eu-central-1.compute.internal postfix/smtp[680133]: warning: run-time library vs. compile-time header version mismatch: OpenSSL 3.2.0 may not be compatible with OpenSSL 3.0.0
I'm not sure if this is actually a problem (mails are sent) but i doesn't sound good either

Apart from the warning being present, there's no problem. When we updated to OpenSSL 3.2 from 3.0 we were very careful to ensure binary backwards compatibility.

We obviously missed the presence of this warning in our testing, so thanks for the bug report! We'll ensure the warning is resolved in a future update.

thanks for the clarification @stewartsmith :)
