UIDVALIDITY when changing UID's).
I won't be long before you'll find an arbitrarily broken IMAP
server. Look at web.de, it doesn't extract headers properly, and the
only "support" they offer is a 01908 (premium rate, 3,63 EUR/min IIRC)
phone support which is likely to be some support that tells users where
to click in their MSIE. Suffice this for a rant for now.
Given that the UID's are supposed to be persistent unless UIDVALIDITY
changes, I would think that fetchmail can automatically decide whether
to do Fast or Slow UIDL during any given session:
[...]
* Whenever UIDVALIDITY changes, use Slow UIDL and the saved MD5's to
update the saved UID's.
Fine.
