dovecot - Oct 2012 - does dovecot interpret any mail headers specially with maildir?

Hi.

For mbox,
http://wiki2.dovecot.org/MailboxFormat/mbox#Dovecot.27s_Metadata lists a
numer of mail headers:
- X-IMAPbase
- X-IMAP
- X-UID
- Status
- X-Status
- X-Keywords
- Content-Length
that are treated specially by dovecot.

It also suggests, that these should be stripped by the LDA (I guess in
order that someone sending you such mail cannot set the status or
keywords, or even "attack you" by setting a bogus Content-Length).


I wondered, when using maildir, are there any headers that dovecote
would treat specially, too?
And which I therefore should strip?


Thanks,
Chris.

Right.

No. Maildir metadata is stored elsewhere.
