Dave,

  Hmmm, first off the username mapping should be in the 
/etc/mail/virtusertable I believe.  Do a "grep kpodmore 
/etc/mail/virtusertable" and see what it returns.  The do the same
command 
(grep) on a "working" account and see what it returns.  May be your
postgress 
database is partially hosed and not re-writting the file correctly on
changes 
(any change to any account will cause it to rebuild the virtusertable)

Also, you can try "/usr/sbin/sendmail -bt" (sendmail in test mode) at
the ">" prompt enter 0,3 kpodmore

and it should tell you what it would do with that address;

then try 0,3 kpodmore@xxxxxxxxxxxx

and see what that says.  Will tell you if the local sendmail is
recognizing 
the account names and address mapping.

Use <CTRL-D> (control-D) to exit sendmail test mode.

Just to clarify;
The kpodmore@xxxxxxxxxxxx address is not one of our accounts,
so it would not be in our database. No one on our server can
send to that account, yet if we send through hotmail or
something then it gets through just fine.
I will try the test mode sending though and see what happens,
Thanx for the help.
