Yes. But, thats not what I mean. What I am saying is that some firewalls can cause issues when telnetting through them to test an SMTP server - It can interfere with the commands you are sending because it knows you arent a real MTA connecting. I've seen it happen plenty of times with firewalls and even some spamfilters (McAfee appliances in particular).. > Please take few seconds and read this post from someone in the sourceforge > forum: > Sorry, but I don't read the forums. > He has the same problem.

And, I'd like to clarify, you dont actually know if you have the same issue as him, because you have only had flawed telnet tests - You still haven't performed a "real" (real server to server or real client to server) test, correct? > I think I will give it a try today and turn assp on.

You can use a test client (Thunderbird/Outlook/etc to connect directly to ASSP to verify if there are "DATA" errors when you establish an SMTP session and transfer a message. You'll just have to customize some of the ports etc. in order to perform your tests. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
