Package: exim4 Version: 4.94.2-5 Severity: normal Dear Maintainer,
when I put my laptop to sleep, then wake it up on another network (which is what happens 95% of the times that I put it to sleep), exim takes 10 seconds to accept any connection until I restart it. Demonstration: hobbes@sphax:~$ date && swaks --output /dev/null --to r...@lybrafox.be --server localho> mer 26 mai 2021 11:14:09 CEST mer 26 mai 2021 11:14:19 CEST hobbes@sphax:~$ sudo service exim4 restart [sudo] Mot de passe de hobbes : hobbes@sphax:~$ date && swaks --output /dev/null --to r...@lybrafox.be --server localho> mer 26 mai 2021 11:14:32 CEST mer 26 mai 2021 11:14:32 CEST I waited a bit before doing those tests, to be sure that the laptop was fully awake. If I don't redirect the output to /dev/null, I can see that the delay happens in the very early stages of the connection, before any smpt happens.
