Hi I apologize for any confusion . Is it possible for users on the internal lan to have both sender's envelope and reciepient envelope check for valid MX and A records .? What we have done in the past is before creating the smtp connection we do a dns resolution on the sender and reciepient , if they are ok we initiate a smtp session everything goes ok . Since mfcheck already did half of the job of dns check I was hoping there was a way to add the check for the reciepient domain existance . e.g. from your host: telnet host 25 1- mail from:[EMAIL PROTECTED] will generate a 533 error 2- rcpt to :[EMAIL PROTECTED] generates no error untill message is queued
