It's possible that this has been answered already and I missed it.  The only
outbound that works with my irex and fastecho is netmail and mailbox
directories.  Everything else ends up in the appopriate directory but is never
tossed.  I recieve just fine.  As a note, one of my email passwords was
corrupted so I'm wondering if it would be a good idea to start from scratch. 
Irex is registered with the max number of nodes.  Game packets and echomail
does not ever get tossed, which I don't understand.
I'm willing to provide *.rex files.
