[BUGS] Missing Mails

[Jerahmy Pocott]

Hi gang,

All of a sudden mails from one of my servers to me is going missing..  
I recently added a fetchmail daemon and changed a mail alias, but it  
wasn't until a few days later that I stopped getting log files mailed  
to me. Investigating I sent mail to my account (lets call it account  
A) from my isps server and from the server in question as well as to  
another address of mine (I will call that B)..

Mail from my ISP to A: Success.
Mail from server to A: Hasn't arrived.
Mail from server to B: Success.

There is nothing in mailq and I'v not received any undeliverable or  
bounced mail messages..

Any ideas on what might be happening? I'm confused..
