The only way to disable the ability to telnet to port 25 is to turn off your mailer. I'm assuming that's not want you want - you just want to disallow the 'expn' command for sendmail, correct? In that case, add the following line to your .mc file: define(`confPRIVACY_FLAGS', `authwarnings,noexpn') Then rebuild and re-install your sendmail.cf file. This will disable the sendmail 'EXPN' command. Aternatively, if you prefer to hack your sendmail.cf file directly, add: O PrivacyOptions=authwarnings,noexpn -- Jonathan
