POP3 and "seen" flag

That the message have been read (RETR executed on it). The "seen flag" is
taken from 'retr' documentation at
http://docs.python.org/lib/pop3-objects.html.

Good to know :-)

No such luck for me.

You're right.
I'm trying to delete only read messages from Exchange server, *another*
client is used for reading. (It's a long story involving me and IT here
...)

Bye.
