Hello everybody, I'm having a serious problem with smtp. I get error messages that e-mails cannot be sent, even signup emails.

This is the message that I get returned:

This message was created automatically by mail delivery software. A message that you sent has not yet been delivered to one or more of its recipients after more than 24 hours on the queue on server1.serve-host.net.

The message identifier is: 1CDe2a-0007FQ-PR
The subject of the message is: Your account for tomtom.be is now ready for use.
The date of the message is: Sat, 02 Oct 2004 09:10:48 +0200

The address to which the message has not yet been delivered is:

[email protected]
Delay reason: SMTP error from remote mailer after MAIL FROM:<[email protected]> SIZE=2783:
host smtp-pandora.telenet-ops.be [195.130.132.51]:
450 <[email protected]>: Sender address rejected:
Domain not found

No action is required on your part. Delivery attempts will continue for some time, and this warning may be repeated at intervals if the message remains undelivered. Eventually the mail delivery software will give up, and when that happens, the message will be returned to you.

My first guess is that there's something wrong with the rdns, as some receiving mail servers accept the e-mails. I went to dnsstuff.com to quickly see where the rdns server problem might be(server-ip: 217.170.21.113). Strangely, my providers 1st rdns has the the correct information, but the 2nd has other information. I'm going to contact them tomorrow, but first I need to know if I'm thinking correctly. So the question is "am I thinking correctly?".

Thanks

Do you host pandora.be, or does someone else?

The real question is "why does pandora.be report user not found for this usre?".

Thanks for replying, to give you some more details:

Pandora.be is a domain from "telenet" , which is one of the largest isp's in Belgium.

So I'm going to test other providers to sort the problem out, and eventually contact "telenet". What about that?

Thanks
