Smpt Blocked By Provider

Hi list,

I know this question must have come up before.
Is there a way to make ASG 7.004 to relay all outgoing messages thru providers SMTP host.
Unfortunately my provider does not allow direct SMTP connections to anyone except its SMTP server.

Thanks

I greatly appreciate your help!!!
However I totally forgot to mention that my applicance is not licensed to do Email Security, thus I CAN NOT access functions described above.

Suggestions PLZ.

Thanks

CREATE a SNAT rule for the MAIL Server to go EXPLICTLY the IP address or better still SMART HOST DNS name of your ISP. with a PF on Port 25 SMTP.

Create a DNS Host object of the SMARTHOST and SNAT your SMTP feed to that.... THE ASG DNS will do the resolving to IP address than MAIL will go to the ISP, also CREATE a DNAT rule to allow MAIL in and again EXPLICTLY allow only a PF SMTP (25) traffic from the ISP to reduce "direct connect" SPAM Mail.

By restricting the IP range of PORT 25 to the ISP only prevents you from being used as a RELAY by third party connections.

Thanks a lot, that worked like a charm and I do not need SNAT since incoming smtp to me is also blocked. However I was expecting an MTA solution of some kind where I would alter EXIM config or smth [:)]

Thanks Again
