E-Mail Blacklist Services Used by BT Mailservers

[accelerator]

Hi

Can anyone tell me the blacklist / known spammer services that BT might be using on their mailservers. I am trying to work out why it's not possible to send to an @btinternet.com address.

Many thanks

all bt need to do is query the sending domain and cross reference with a service liek teh following Blacklisted Domain | E-mail Server | Black-List

the lists are synced so if your mail server is on one .. you aint gettin through

The headers of the bounce-back you receive should give you the answer. Unless BT have set it up so that a bounce-back is not sent.

I think I read somewhere they use the same anti-spam system as yahoo; can't remember where though.

I also have a problem sending to them using php list, i'm going to put SPF (Sender Policy Framework - Wikipedia, the free encyclopedia) on my domain as i've read in forums that this will help.
