[Dovecot] 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: that are treated specially by dovecot.

• X-IMAPbase
• X-IMAP
• X-UID
• Status
• X-Status
• X-Keywords
• Content-Length

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.
