Hi,

I have several servers configured with exim4 and only on one of them I have error messages related to TLS. When I use the adjective "strange", I do it because I have no idea why sometimes the error occurs and sometimes not (sorry).

The server where the errors appear has exim4 4.96 installed with debian 12 and gnutls 3.7.9. In the rest of the servers (no errors here) is exim4 4.94.2 with debian 11 and gnutls 3.7.1.

All messages are delivered correctly.

Examples of this behavior are shown below:

- Sending to gmail: H=gmail-smtp-in.l.google.com [142.250.27.26] TLS error on connection (recv): The TLS connection was non-properly terminated.
- Sending to yahoo: no error
- Sending through an external relay: H=email-smtp.eu-north-1.amazonaws.com [13.48.208.88] TLS error on connection (recv): A TLS fatal alert has been received: User canceled.

And so on with some others ...

I have read several messages on this mailing list that don't give importance to these errors, but I don't understand very well why the error appears with some servers (gmail, relay aws) and not with others (yahoo and others). Does it have to do with the new versions of exim4 software, gnutls or debian? I would like to have some more information, if anyone has it.
Are we sure that there is no problem with these errors?

Thanks for everything
