Smart host SMTP authentication over mail.btconnect.com

Hello
I have an SBS 2003 downloading with POP3 connector (from client's registered domain) and sending out through smarthost (mail.btconnect.com). Day-to-day in and out flow of mail is ok (after registering client domain with BT Business!)... I then configured mail forwarding for two user accounts to send a copy out to (in this case) 2 x Blackberry addreses. The copy forward emails are generated on the Exchange 2003 no problem (you can see them queuing) but when they are released onto mail.btconnect.com they get EATEN!!... good old BT!

As always BT claim never to have seen this before and arent much help (as always). One chap told me to try and "bring the SPAM count down on these copy forwards..." by configuring SMTP Auth in the (SBS) smarthost using our btconnect.com email address details (Basic Authentication). I tried this but the SMTP Auth was rejected!!

Tested this with Outlook Express running on the SBS and mail was sent ok.

I have read muchos bad stuff about mail.btconnect.com and been advised to change my client to another ISP... am i bashing my head against the BT brick wall or is there a solution to this mess?

Does anyone know if Exchange 2003 'Outbound Security' on the Smarthost needs to be configured differently from setting it up in a mail client like Outlook Express/Outlook?

Thanks
Mark

This is probably BT's anti spoofing system.
Automatic forwarding will soon be impossible because it looks like spoofing. The email appears to be coming from another address - not yours and that is why it is being rejected.

Have you tried setting up another SMTP connector for just the Blackberry domains and sending it directly to the Blackberry mail servers?

It means breaking one of the rules with SBS and doing it manually.

Hi Simon

Thank you for the instructions. When i config the new SMTP connector should i use mail.btconnect smarthost?

Please forgive my ignorance.

No - the point of creating a new connector is to send to Blackberry directly.
Therefore you will need to send to the Blackberry mail server. You can find out what that is by doing an MX record lookup on the domain.

You have to change the cost in the SBS Connector so that * is cost of 2.
