Re: dynamic DNS and SPF?

2004-06-03 09:46:09
thanks for the reply. i know i get a lot of viruses and stuff from
cable modem users, but i also have a virus scanner on my mail server
(mdaemon) and that gets rid of the crap. ill see about using my ISP's
mail servers. might be quicker/better.
Thanks for all the info!

ok. thanks for that. ill try that out now. is there somewhere i can
test this though? like send an email and get a reply saying fail or
pass or what have you?

Normally I'd just say send me an email directly and I'll post back the
Received-SPF: header that my mail server adds. However, I don't accept mail
from hosts with reverse DNS in the cable.ntl.com domain as I'd just get
inundated with viruses if I did. You may find other people with similar
policies regarding mail from cable modems or in fact dynamic IPs in general.
You may end up sending mail to those domains via your ISP's smarthost, in
which case you'll need to add the IP addresses of NTL's outgoing mail servers
to your SPF record.
