[Fetchmail-users] Downloading 'seen' email?

[Hylton C. (ZR1HPC) <hy...@co...>]

I have been noticing that some email, although possibly read on Gmail 
and marked as unread, is not downloading to a local mailserver.

Looking at the log for the last retrieval I see the line of:

***Start***
fetchmail: 155 messages (67 seen) for 72h...@gm... at 
pop.gmail.com (15312088 octets).
***End***

Looking through the log I see that the number of messages seen changes 
yet never hits 0.

My fetchmailrc is:
***Start***

#set daemon 300
#set syslog
#set postmaster "hylton"
set logfile /var/log/fetchmail.log
poll pop.gmail.com
protocol POP3

user "mygmailaddress" there with password "mypassword": is "hylton" here 
keep ssl
#7mda "/usr/bin/procmail -d %T"
***End***

Whilst there may be other errors in the above file, my main concern is 
how to retrieve the 67 'seen' messages as they are not on the local 
mailserver but are listed as unread on Gmail, and are sitting in the Inbox?

Comments?

P.S: If this has been covered previously, please direct me to the 
archive location of messages for fetchmail so I can use its search 
function and hopefully find the answer.
