Great... and I expect that this ("no headers from the maildir files are interpreted") applies also, when one "imports" mails the first time.
With import I don't mean via IMAP, but plainly moving e.g. a maildir ++ tree under dovecots mail location.
Yeah. So that means: From a "security" point of view, when using maildir (!)

Right. The only special case is X-UIDL: header, which is used for POP3 UIDLs but only if pop3_reuse_xuidl=yes (which isn't really recommended nowadays as there are other ways to do it).
I just wondered because when I looked through my mail archive (currently as mentioned, under Evolution)... many emails already had X-UID and X-IMAP* headers.... (set by the remote side, not by Evolution) ... and in no case these should be able to mess around in my dovecot :)
If you migrated from mbox format it could have brought those headers to maildir. They're anyway not used for anything by Dovecot.
