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?
Thanks, Wolfgang

I'm running 2.2.36 (as provided by openSUSE in their server:mail
repository) and at least at one of my systems LMTP is crashing regularly on certain messages (apparently a lot of them).
Sometimes (but not always a backtrace is posted to the logs:

Looks like it's because of the "mail_attachment_detection_options = add-flags-on-save" setting. What mailbox format do you use? It's currently broken with mbox and in v2.2.36 with Maildir (which was fixed in v2.3.2).
I'm indeed using maildir so this is a known issue and yes I use mail_attachment_detection_options=add-flags-on-save (or rather I tried to but now have to disable it). Not sure when I get to upgrade to 2.3.x.
Thanks, Wolfgang
