It might be that QT 5.15.1 is related to this problem.
Comment 2 Stefan de Konink 2020-10-31 17:26:59 UTC 
I'll close this bug, but I want to specifically state how it was triggered and how it can be "resolved". For years I have been using Postfix with Letsencrypt. Specifically I use the privatekey and certificate from acmetool.

After my last QT and Trojita update this combination did not work anymore resulting in an error. After noticing in strace the problems occured on the Lets encrypt root certificate I wanted to try if changing towards the fullchain certificate would help. It did. This also explains why IMAP was working, because it already used the fullchain file.
