Dear Swinog members
Until now, we provided an authenticated smtp-server for our customers
and a separate "open" smtp-server for customers with email-adresses
from other providers. We would like to shut down the relaying server
and have the customers use the smtp-servers from their mail-provider
(gmx, gmail, bluewin etc.).
Now we found out that bluewin doesn't allow authenticated smtp-relay
from users outside their ip-range, so all our customers with
bluewin-mailadresses would have no smtp-server available.
I am sure that some of you had the same issue and would be interested
how other (small) isp's have resolved this problem.
Thank you,
Roger Schmid
