I have an Exchange 2003 Frontend/Backend environment and I want to know if
the Frontend server should be sending external SMTP mail. For example, when
users on my private network send mail to external domains, the mail is being
sent from my Backend server (i.e. Backend server is doing MX lookups and SMTP
communication directly with outside mailservers). I would like the frontend
server to do the SMTP sending. I have tried to setup an SMTP connector with
Exchange Frontend as the local bridgehead and address space set to * and cost
of 1 (no other SMTP connectors). Outbound mail gets queued up and never
sent. When i reenable the SMTP connector on the backend i get an
Non-Delivery Report stating #5.7.1 smtp;550 5.7.1 Unable to relay for
joshp@*********** for every message i tried to send.
Any help would be greatly appreciated.
You're on the right lines. Check on the BE to make sure the SMTP VSI
does not have any "smarthost" listed as that'll cause some headaches.
Then as you have seen, the Routing Group and SMTP Connector (that was
what you created, right?) should indeed be created with the FE as the
local bridgehead in it.
