mail missing between exim and mutt

[Mark Copper <mcopper@titaninterface.com>]

Hi,

I would like to request help understanding how some email went missing.

exim's log shows the missing pieces going into maildir:
   2008-08-26 18:23:08 1KY7sS-0003mR-Be => me <myaddress> R=local_us er T=maildir_home

fetchmail should have retrieved the mail:
   poll myserver proto imap 
       user "me", with password "secret", is "me" here, ssl

The mail log shows emails being retrieved and flushed one by one:
   Aug 28 00:17:38 algol fetchmail[2677]: reading message me@myserver:1
   205 of 1231 (804 header octets) (853 body octets) flushed

Only I ended up missing a number of emails.

Where could the weak link be?

Thank you.
