<p><span style="font-family:monospace">Hello,</span></p>
<p><span style="font-family:monospace">this is more a question for
ideas and support, because a bug cannot be proven.</span></p>
<p><span style="font-family:monospace">There is a problem with the
mail system on a server, that does not receive emails from
certain providers any more.<br>
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:</span></p>
<p><span style="font-family:monospace">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)'<br>
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]<br>
</span></p>
<p><span style="font-family:monospace">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.</span></p>
<p><span style="font-family:monospace">The problem exists since </span><span
style="font-family:monospace"><span
style="font-family:monospace">2023-02-15 so the idea is to
search what has changed.<br>
The only thing that has changed is that an automated security
update has happened:<br>
</span></span></p>
<p><span style="font-family:monospace">Start-Date: 2023-02-15
07:38:27<br>
Commandline: apt-get upgrade -y -o
Dir::Etc::SourceList=/etc/apt/security.sources.list<br>
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)<br>
End-Date: 2023-02-15 07:38:32<br>
</span></p>
<p><span style="font-family:monospace">That's the reason why the
question is placed here.</span></p>
<p><span style="font-family:monospace">The changelog only tells
about an "Fix double free"</span><span

<span style="font-family:monospace"></span></p>
<p><span style="font-family:monospace"></span></p>
<p><span style="font-family:monospace">It makes no sense that this
bug was needed to avoid routing problems!?</span></p>
<p><span style="font-family:monospace">Is there any other idea for
the reason of the problem?</span></p>
<p><span style="font-family:monospace">Best regards<br>
