MSN.com email delivery problem

Anyone have MSN contact or white list info?

[Learning Curve]

I received an email from a brand new subscriber who said they didn't receive the confirmation e-mail for one of my publications.

A quick check showed that no one with @msn.com who subscribed in the last two days (and probably a lot longer) has confirmed. I assume MSN is filtering or otherwise messing up my e-mail.

Any ideas on solutions?

The thread below says MSN email has a lot of problems. [webmasterworld.com...]

I have been having the same problem with .msn email accounts since the first of December.
At this time I have has 43 back and forth emails with [e-mail] trying to get it fixed. No Joy:(

I used to have problems sending emails to MSN using SMTP Server on IIS. It had to do with our server's firewall, which was unable to recognize some ESMTP commands. It turned out the firewall didn't recognize the commands, and filtered them out, which would then cause SMTP to fail to certain mail hosts that requested ESMTP commands, especially MSN.

This happened to us on a Cisco PIX router I think.

HTH...

I am having this problem with MSN too. My SMTP server calls up theirs (smtp-gw-4.msn.com) and gets hung up on immediately, without receiving even the initial line from the server. I assumed this was some kind of IP-address spam-block too, and wrote to [e-mail], but then when I tried connecting to the server repeatedly by telnetting to port 25 (from the same IP address), I discovered that every 10th or 20th time it would actually connect, and now I have tried sending a complete message (manually, using TELNET after trying to connect about 25 times) and it accepted my message. So now I don't think it is an IP address block (or at least, not a very good one), the MSN.COM mailserver must be overloaded or misconfigured or something. If anybody else knows anything more about the problem of only being able to connect to smtp-gw-4.msn.com once out of 20 tries, that would be helpful.

Post the SMTP respones here. I am pretty sure this is the same issue i had with MSN. You will probably need to reconfigure your firewall to not do port 25 filtering.
