SmartHosts - 8.Nov.2006 2:29:52 PM

Hello

I hope someone can point me in the right direction, here is the situation and problem.

I am setting up a new exchange 2003 server (used to be SBS 2003) All seems to be working but, when I change the SMTP connector from "Use DNS to route. . ." to "Forward Mail through" and I put in a valid smtp server (from our ISP) when I now try to send messages i get the error,

There was a SMTP communications problem with the Recipients email server. . . . . .Not Permitted

the live and existing SBS server uses the SMTP server of the isp without any problems. If I change the connection back to DNS routing the mail is delivered fine.

Any ideas where the problem might be?, I am new to Exchange 2003 so it might be a small thing but any help would be great.

Thanks
MrLoaf

Your ISP must allow your Exchange server to relay through it. Do you know if they said you could relay their server?

Hello

We currently have our live server (SBS2003) connected and using the smart host provided by the isp (smtp.btclick.com) the pre-production server that I am busing testing and setting up connected to the same out going connection as the current server and gets this error, but seems to work on the DNS setting, but I know that the DNS setting does not work for all domains.

Thanks

This is more than likely because your ISP has to enter the IP of your pre-production server as a permitted relay host on their smtp.tclick.com server.

JChong,

you were 100% correct after long and "your call is important to us phone calls" I eventually got thought to someone who was able to enable a relay on the BT ADSL line. They added the new domain and after 12hours the problem went away, Many thanks for the help.
