Pokud to jde vzdy na stejneho (neexistujiciho) uzivatele, lze snad 
nejak pres virtusertable rict, ze ten uzivatel fakticky neexistuje (tj. 
odesilatel dostane "550 user does not exist" jiz po zadani RCPT 
TO).

"Systemovejsi" reseni je dat blok na "MAIL FROM", pokud je 
odesilatel vzdy stejny. (access.db)

Pokud jde ten clovek z dial-upu, lze tez blokovat pomoci DUL (viz 
www.mail-abuse.org).
