Works great!  I had a problem at first, because I had "Use for all outgoing mail, regardless of address selected" under Tools/Internet Options/Sending (SMTP).

I have 2 XP machines on a network using the 2WIRE HomePortal 1000HW. They both access the same Pegasus mailbox folder under different user names (following these instructions: http://community.pmail.com/forums/post/2476.aspx). Having little network experience, I'm wondering, can I send messages between users of this setup with Pegasus, without sending it out over the internet?

Sure, mail sent with the user name only in the email address will be delivered directly to the other users mailbox.

If you leave the @domain.com off of the To address and just send the email to the user mail name, I believe that what you want will be accomplished.
