sorry for the empty mail. GMail UI confused me ;-) I finally did a short term update to 2.3.2.1 and it seems to work (at least no LMTP crashes to be seen).
But one other thing: One of my other mailservers is still on 2.2.36 but I could not find any crash in the logs and also no other weird behaviour. While I also use maildir there one difference in configuration is that it's using mail_attachment_detection_options = add-flags-on-save exclude-inlined I also tested with an explicit mail including a file attachment because I was not sure if I received an attachment during log retention time (this server is just serving 5 personal accounts). That's fine for me but I do not totally understand why it works (or at least not crashes). I still have to verify if the flags are correctly applied though. In any case since I performed one upgrade to 2.3.x already I will be able to update the other servers soon anyway. Just wanted to give that feedback/observation.
