Hmmmm... very interesting. I did not talk with user3 (the external user)
and can not say if this problem just happens when users from the local
network send mails to him. So, let's do it.
Another interesting point is that both user1 and user2 (the local ones,
sending mail to the external user) are sending mail through Gmail.
I can not also say if user3 is using POP or IMAP to read mail, that's
another point to check.
By the way, one can not always be sure of what the users are really
doing. :) It's time to grab more information.
Greetings.

Im not sure if the above happens when using IMAP, but I guess it could if the
IMAP Session doesn't tell the server to say hey I downloaded all of you so
clear the file for new messages.
