Re: [cobalt-users] RAQ 4 Email Relaying

["Ray Healy \(Data Net Services\)" <ray@xxxxxxxxxxxxxxxxxxxx>]

Thanks for everyone input regarding mail relaying.

I have decided to go with the "norm" as suggested to protect not only myself
and my clients but the rest of the web by getting the users to send mail via
there own ISP dialler.

As far as I believe it is only BT and AOL that do not allow you to send mail
through their mail server unless the client uses the supplied email address
from them or advise BT and AOL of the Domain name so they can enter it into
their records (after about 3 weeks - so I have been told). But anyway there
are many other diallers out there (Freeserve for instance) and ADSL.

Thanks again for all your comments
