Domino/NOtes anti-spamming

[<pyb () passport cadrus fr>]

   Hi,

   Does anyone of you know if the Domino/Notes server, when used as a mail
gateway (between SMTP and Notes Mail) can be configured to avoid spamming and
the like (just as sendmail can be hacked) ?
   And, if the answer is yes, can you give me some pointers to where I may
find the proper information ? 
   TIA,
