This 'feels' like cache management misconfiguration to me.  Not sure whether in Tbird &/or Dovecot, or what to look for specificially.

Hints as to cause/fix of this attachment issue?  Or event what/where, specifically, to log?

I see same symptoms when opening a mail in thunderbird 2 or 3 weeks after I received it, without moving it in another folder. Burt using "repair folder" in TB, I get it back, so for me it looks more like a TB cache problem.
