If I run `fetchmail -vvvc', the tail of output shows:

        1324764631.3974 = SEEN
        1324764631.3975 = SEEN
          [...] snipped 17 more similar line

        1324764631.4032 = SEEN

Even if I've just run `fetchmail -vvva'  making sure fetchmail pulls
down any `seen' messages.

Looks like fetchmail is reporting  20 seen but not retrieved messages.

Is that right?

Also have `fetchall' in ~/fetchmailrc uid and passwd MUNGWED:
  
  # set timeout 40
  # set daemon 600
  # set logfile /home/reader/t/var/log/fetchmail.log
