Relaying mails

[joemon]

Hi,

I own 2 server. The IP address of first servers is blacklisted. I would like to use the mail server of the second server for sending mails from my first server. I did all possible steps, but I am still getting an error that relaying thru the second server is not permitted, while trying to send mail from the first server. Please advice. This is really urgent.

I'm having a similar problem. I asked a network engineer, and he said it may be network connection or firewall issues.
