Hello

We have alot of 3rd party applications and SQL servers that must use an

internal SMTP server to send internal email, (the email is sent from an

accepted domain) I used to be able to point these servers to an Exchange

2003 server and thats all that was required, but now when i point one of

these servers to a HT server, it doenst work, we get "unable to relay" which

to me is a little confusing becasuse the FROM: address in the email is

comming from an accepted domain, so this shouldnt be considered a relay

should it? How can i configure a receive connector so it will allow internal

severs to use it to send email as an accepted domain? The servers cant pass

credentials

thanks

Relay means accepting SMTP mail with destinations outside the organization,

and has nothing to do with the purported FROM address, which, of course, can

be completely forged and therefore has no value as an authentication

mechanism. If those servers require relay, and you're sure that opening

relay on an Exchange server won't expose you to being a spam agent, then go

ahead and do it.
