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

Hi Roger,
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.
That's not entirely correct:
smtpauth.bluewin.ch will relay mails from non-bluewin-ip-ranges

Hi,
Thank you for clearing this up. So we have to give bluewin-users with
free bluewin mail-accounts an smtp-account on our servers I think.

Our helpdesk will disable it
