Hello,
this is more a question for ideas and support, because a bug cannot be
proven.
There is a problem with the mail system on a server, that does not
receive emails from certain providers any more.
The sender of the emails don't get any notice that the emails are not
delivered and there is only one sender that could provide an error
message. This is:
2/17/2023 12:43:19 PM - Server at PAWP195MB2418.EURP195.PROD.OUTLOOK.COM
returned '550 5.4.316 Message expired, connection refused(Socket error
code 10061)'
2/17/2023 12:33:05 PM - Server at domain.de (xx.79.98.xx) returned '450
4.4.316 Connection refused [Message=Socket error code 10061]
Searching the internet shows that will be caused by a routing problem,
but the mail system generally works and emails are received from other
senders.
The problem exists since 2023-02-15 so the idea is to search what has
changed.
The only thing that has changed is that an automated security update has
happened:
Start-Date: 2023-02-15 07:38:27
Commandline: apt-get upgrade -y -o
Dir::Etc::SourceList=/etc/apt/security.sources.list
Upgrade: libgnutls30:amd64 (3.7.1-5+deb11u2, 3.7.1-5+deb11u3),
libgnutls-dane0:amd64 (3.7.1-5+deb11u2, 3.7.1-5+deb11u3)
End-Date: 2023-02-15 07:38:32
That's the reason why the question is placed here.
The changelog only tells about an "Fix double free":
https://metadata.ftp-master.debian.org/changelogs//main/g/gnutls28/gnutls28_3.7.1-5+deb11u2_changelog
It makes no sense that this bug was needed to avoid routing problems!?
Is there any other idea for the reason of the problem?
Best regards
karsten
