[Samba] Samba and sendmail.

You might find that sendmail is configured to do expansions on the + 
character, I did once look into the sendmail config, but gave up in the end 
and now use postfix (much easier to understand.)  I believe the + 
operator's default behaviour in sendmail is to forward the mail to the 
machine before the plus and send it to whatever is after the plus as a user 
on that machine i.e. forwards to Piotrek at JEDYNKA in your case.  sendmail 
probably cannot resolve the hostname JEDYNKA as it isn't a host but a 
domain.  You may find the easiest answer is to change the winbind char to 
something else (although I don't know what!).
