What is the function of the X-UID header in mbox format?
Dovecot gets IMAP UID from it. The header isn't supposed to be sent to clients at all, but the current code still does..
Running Thunderbird 0.5 against a Dovecot IMAP server with mbox format, Thunderbird displays these UID numbers in the message list, which is fairly useless -- I want a numbered list of my messages starting at 1 (which Pine, for example, is happy to provide).
Does Thunderbird actually use the X-UID header, not just the IMAP UID that gets sent separately? If the X-UID header is the problem, it's then Dovecot bug that it shows the header to Thunderbird.
If Thunderbird just uses IMAP UID and shows it, I agree it's pretty useless but that's for Thunderbird to fix.
I'm just wondering whether this is Dovecot's fault, Thunderbird's fault, or an ambiguity in the mbox standard.
IMAP clients shouldn't know anything about what kind of mailbox format is being used in server side.
