AT&T and Cellular smtp messages not being sent

[Mike Weiser]

Some reason both ATT and Cingular phones have quit accepting smtp messages from our Pagegate server. I can access the internet and TAP works fine for all other recipents. Below I included a log from our dialer.

Thanks

We removed the log entries from the post, so that no personal information is visible (ID/Pins, Names etc.).

It looks like there may be a firewall or ISP blocking port 25 traffic (SMTP).

What is the result of a manual telnet connection from the PageGate machine, to the ATT mail server "mta01.cdpd.airdata.com" using telnet on port 25?

To test do the following:

Go into the command prompt on the machine and type (without the quotations!):

"telnet mta01.cdpd.airdata.com 25"

You should receive:

"220 mta01.cdpd.airdata.com (IntraStore TurboSendmail) ESMTP Service ready"
