Title: After most recent update ver. 0306-0 SMTP now conflicts with port 25 (Outlook)
Post by: The MacKae on June 21, 2003, 02:17:56 PM
All was fine ... then auto update. Now Avast errors out with "Can not protect outbound mail due to conflict with Port 25". Port 25 is the Outlook port. I am running 2K with a PIII processor. Only other new software is Macromedia Fireworks and I find no conflict there

Actually this is a new feature in the latest update - it warns you that there is a problem. Otherwise, you wouldn't know.

The problem is that another program in your system is already listening on port 25. Only one program can do this at a time. And because this is how the Internet Mail provider works (by default), it gives you a warning that it can't do its job.

It may be worth trying to find out which program is taking up the port. Don't you have a mail server software on this box? A mail proxy? A security filter? For instructions on how to find out the name of the process that has allocated the port, please see my post here: http://www.avast.com/forum/index.php?board=2;action=display;threadid=539 .

Hope this helps,

Thank you. I will check, but I believe my ftp uses that port, but it only uses it when active. That is why I originally ignored it.

FTP? Hardly. I really doubt FTP would ever want to listen on port 25, which is traditionally reserved for SMTP (e-mail) traffic.
