Unable to relay via SMTP Server


Hi all,
Email clients------SSLVPN Gateway--------Email Server

Iam have some Email clients present on the back of the SSLVPN Gatway.I use IE to login to the SSLVPN Gateway and proceed with the application access. The SSLVPN Gateway just proxies the requests towards the Email server port no 110(POP3). My Email clients does not give error when they send and receive any mail.But whatever I send its not received on the Email server. Its going to a Black Hole.When I manually telnet to the Email server via 25 port no. its saying "unable to relay to the destination mail address".Please let me know what might be the reason for this failure.I see the same behaviour with IMAP also.Please provide me some links for my Linux configuration.
Thanks
siva

"unable to relay to the destination mail address"

this is probably due to your smtp restrictions are not allowing relay to any non-local destination.


To setup an email server that relays mail anywhere it needs to only relay for local users, which is the default. Your ssl connection should be seen as a local connection therefore the default settings would allow you to send anywhere.

You do not want port 25 to allow relay, only the internal connection. Otherwise you would be running an open relay.

You can have a look at this and maybe get some idea about your setup.

In the discussion area of that post there is also some updated ideas that may be useful.
