SPAM Blacklist

~J~ · 6 Mar 2008 at 10:52

Anyone know if there's a website(s) that I can enter either an IP address or Exchange server name and see if we're on a blacklist?

We've sent a few emails out to some clients but they've been refused and we're wondering why we've gone onto a blacklist.

Everyone of the 'blocked' emails is a BT customer, but can't seem to see where to test and indeed to say "Oi, BT, we're not spammers"

Any thoughts?

Try this one, does a few at at time, the bigger ones by the looks of it.

Basic stuff but does your Exchange server have a reverse PTR and a hostname which resolves?

Give this one at mxtoolbox a go.

Cheers folks, will look into them.

We've narrowed it down a bit. BT Connect customers get our emails, but BT Internet don't! Bit weird.

Basic!!

No idea mate, I'm not a techie. All I know is that the emails are sent via an IronPort system.

If you want to send an email to [email protected] from the system (reference OcUK in the subject line) I'll tell you if anything is obviously wrong with it which would cause BT to reject.

Brilliant, cheers for that. Will send you an email tomorrow morning.

Thanks.
