follow up question. Is there a commit which is reasonable to backport for me into the packages or is it too intrusive or based on heavily changed code?

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.
