You already know what to do, I'd add that I've known BT to be quite
difficult about PTR records, even on 'business' accounts with static IP
addresses. There will already be one of a generic kind, along the lines
of 'adsl-12-34-56-67-pool.btconnect.com', but this is not likely to
impress other mail servers. I have my own server configured to reject
SMTP connections from addresses with PTR records of this kind.
The bad news is that many mail servers, particularly those of ISPs, will
expect a 'proper' PTR record of 'example.domain.com' form, and many
(including mine) will expect there to be a valid A record for
example.domain.com which points back to the IP address. I have not found
it necessary for the PTR-A pair to match the MX record or HELO string,
as mine do not and I have no problem sending mail to AOL, which is
Certainly two or three years ago, BT wasn't good at organising this kind
of thing. If they are still not willing to do it, then the only way you
can send mail reliably is through another mail server which is
considered 'respectable', such as an ISP's SMTP server. Check if your
account with BT includes the use of an SMTP smarthost, as it is a
facility you may want to use for other reasons.
One of my customers insisted on using BT as ISP, against my
recommendations, and took out a 'business' account. This turned out to
have no smarthost facility and a fixed IP address that had a 'generic'
PTR and was on a number of blacklists, none of which BT was prepared to
do anything about. I ended up giving him an authenticated SMTP account
on a web hosting package that I rent, to use as a smarthost. BT's
recommendation, and I kid you not, was to use Yahoo for email. I think
even today, BT subcontracts some parts of its email handling to Yahoo.
