thks for the mailscanner tool

[vinay poojary]

Dear Sir,
   
  It does not requires any username / password for the auth .The user can use his own username / password and only change the email address in the email client .So to stop email spoofing in u r own organistaion is difficult .
   
  can we have any option for email spoofing in mailscanner .
   
  Regards,

i agree that this can taken up at a different level (read as catbert), i 
also think that poor passwords are also responsible for sender spoofing. 
We had a case a year back, where a "secure" SMTP server was used for UBE 
(via a korean IP), using authentication that was quite easy to guess 
(password = username). Now we now enforce stricter passwords ;-)
