Darrell, On a win2k box, there is really nothing behind port 113. It goes by many names, auth, identd. Many email servers just look to see if the port exists but they retrieve nothing for there is no daemon or service using the port.

Sent: Friday, 09 August, 2002 00:09 To: [EMAIL PROTECTED] Subject: [IMail Forum] Port 113 Since I put our Imail server up I have noticed a ton of attempts to access our mail server on port 113. All of these appear to be from other remote mail servers. After some research I found that port 113 is used by mail transport agents (sendmail in particular) in an attempt to identify the name of the user sending email. What reason would the remote mail server care about the user who was sending the mail? And if they found this information what do they use it for?
