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 IF the mailaccount belongs to a non-free Bluewin/Swisscom 'Abo'.
+-------------------------------------------------------------------------------------------+ | Pay account (= Mailaccount | - Can use mail.bluewin.ch from bluewin-range | | is 'attached' to an ADSL abo | - Can use smtpauth.bluewin.ch from EVERYWHERE | +-------------------------------+-----------------------------------------------------------+ | Free account | - Can use mail.bluewin.ch from bluewin-range (of course..)| | | - Can use smtpauth.bluewin.ch from bluewin-range | | | - Can NOT use smtpauth.bluewin.ch from non-bluewin IPs | +-------------------------------+-----------------------------------------------------------+
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.
Otherwise spammers would open 100th's of free accounts and use them to send spam from non-bluewin IPs :-/
I see the problem, but perhaps something like a captcha would also be sufficient to prevent this.
