Dear all,
I'm using Microsoft office Outlook 2007 with Win Vista. I can receive an
email with many accounts but can't send an email from any of them. When I
test account setting, Logging onto incoming mail server POP3 is completed but
sending test email message is failed. The error is "the server responded: No
550 RDNS entry for 115". Before, I could send an email but I can't now. Pls
help me!!!

You're sending IP address does not have a reverse DNS entry and the receiving
mail router is rejecting the message because of it. This is something you
should be discussing with your mail service provider.

I'm using AVG anti virus. I've used this one for long time, but the problem
just happened recently.
