Need some help - mail being filtered as Spam, but don't know by whom

seamus

OK, a little background.

I'm rolling out Exchange to all of our users. We don't have an internet mail host - another company (eurokom) handles all of our incoming and outgoing mail. Our mail servers just relay the mail to theirs and forget about it.

A few users have blackberrys, and the way it's worked thus far is that we set them up at mobileemail.vodafone.ie, and then set up an autoforward on their mailbox to copy all mail to their blackberry account.

Then I moved one such user to Exchange, set up the mail forward in Exchange, and he started having trouble. Specifically, mail from external sources will not relay onto the mobileemail account. This is pretty much as you would expect. But I can't find out who is refusing to relay the mail. Since it worked on the old POP/SMTP mail server, the likely suspect is Exchange, but the Exchange server is wide open. It's not set up to refuse to relay under any circumstances (This doesn't bother me that much because the host is on a private network).

So I set up a similar forward for myself to get my hands on some of these error messages. And they're all being refused by the same host - who in theory shouldn't be dealing with the mail. Basically, I sent a mail from my Gmail account to my work account. The gmail account then receives an NDR telling it that the mail to the mobileemail.vodafone.ie account was caught by a Spam filter. I do of course receive the mail on my work account.

The only thing that's confusing me is that the host who sends the NDR to Gmail is my exchange server - though it may just be relaying an NDR from another host. The full mail with headers is below. I'd really appreciate it if anyone had insights on this.

Does is it only happen when trying to forward to vodaie.mx1.eu.blackberry.com ?

If you setup exchange to forward the mail with direct smtp via dns does it work?

Blackberrys broke my heart for a long time, Consider a move to BES, I know that doesn't help you much with _this_ issue

Cheers, but I managed to get it sorted this afternoon.

Turns out our mail provider was blocking the relay. So I got them to set up a rule whereby we could relay mail from any domain to the mobileemail.vodafone.ie domain, and we're sorted.

I've just installed a hulking big Exchange server now which I'm going to move everyone onto, and I've been told that 6 more users are getting Blackberrys, so I'm very tempted to tell them they're going to need to pay for a BES too.

It's not very exspensive, I think vodafone do it for about 450?
