Notes/Domino 6 and 7 Forum : SMTP Protocol Returned a Permanent Error

Hi Admins,

we have just migrated (from exchange) to R6 - and now some strange mail problems:

The clients have their (auth) smtp and their pop accounts - and send mail "through domino server".

The auth smtp account is with login name and password (because our ISP needs auth smtp).

Now we are sending our eMails to the Internet with different success: Some are routed fine, other got smtp errors:
============================================

==============================================
so... gmx is OK
but... web.de "don't like us".

I'm really glad for any good idea :-))

[I'm not a prof admin.... when i send internet mails via server, must I switch off the loginname/password?]
