I fgreped our quite big spool, - it is quite usual for clients with windows
mailers to have this X-UIDL header attached to their mails. Correct, pop/imap
servers add this, and yes, they can be recompiled not to do this. 

Unfortunately, it's quite hard to dig out the nessecity of this header, but 
still, I doubt if it's correct to trash such mails, - you risk to loose half
of your windows-based folk's mails. I tryed to correlate fgrep 'X-UIDL' results
with the 'X-Mailer' fgrep results - it's the only what fits - almost 90% of
mails issued on _any_ type of windows have those X-UIDL. Still, I am stuck with
the following now, the scheme of mails passing: 
<client/windows> - <smtp> - <sendmail&&procmail> <-- NO pop or imap servers
here, and still those mails have X-UIDL.
