It *is* possible to force a large X-UID, if the user has an empty

Yes, but only if it's the very first message for the user. Afterwards
even if user expunges all the messages, there are two things that
prevent this from being possible: index files and the UW-IMAP style
"FOLDER INTERNAL DATA" message.
You could also prevent this completely by stripping the X-UID header
in your SMTP server or LDA. For example Dovecot LDA strips all the
Dovecot's internal metadata headers.
I guess the UID renumbering could be done some day, but for now I
think it's just way too much trouble with not that much benefits.

.. I've added
/^X-UID/ IGNORE /^X-IMAP/ IGNORE
to header_checks on each of our postfix servers -- are there any others I should be aware of?

Fair enough, I agree it's a very unlikely situation.

"Content-Length",
"Status",
"X-IMAP",
"X-IMAPbase",
"X-Keywords",
"X-Status",
"X-UID"Quoting Timo Sirainen:

Do I understand this right, that everybody using dovecot and not deliver as LDA should strip these headers in the MTA/MDA? Does dovecot really need this headers, even with maildir? I thought everything is stored in the filename...

I'm only talking about mbox here. With maildir these headers aren't treated in any special way.
