I agree it's crazy - but a friend's e-mails are bouncing coming from his ISP, but OK from anyone else. When he called his ISP, he was directed to these sites, which were showing errors, which are now magically cleared up. So, I'm guessing the problem was on the test client's end all along.

thanks!

All,

I've got a pair of domains running courier-mta - one personal, and one business. Both of them show up with error conditions when the mail tools at dnsstuff.com and dnsreport.com try to verify them, with the following messages:

ERROR: I could not complete a connection to any of your mailservers!

mail.sourcelabs.com: Timed out [Last data sent: RCPT TO: ]

This is a transient problem.

Can some of you try these tools on your own mailservers, and tell me if the problem is my configuration? Or are these tools just incompatible with Courier?

these tools just use smtp. they don't care if you use courier or other.

The issue is that there are some ISPs out there who are using these tools to determine if a domain is valid or not, and who are not sending mail to either of my domains because of these tests.

ahuh? where did you got this? nobody sane is gonna try dnsstuff before connecting to you!
