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.
