Here you go...

rcpt to:Martin
550 5.1.1 Martin... User unknown

and in maillog

Jun  1 19:26:01 fileserver sendmail[1058]: m51IP3GA001058: Martin... 
User unknown


but the entry Martin is in /etc/passwd as follows...

Martin:x:518:518:Martin:/home/Martin:/bin/bash



BUT if I change the username to be all lowercase it works - go figure!


:-(
