Hi all

Since Weeks we steadily get complaints from different customers (sometimes 
sending mail via our server, sometimes with own servers, sometimes using 
mailservers of other ISP) trying to send email to Bluewin Hostcenter 
Customers.

Their emails are being rejected by mail-fwd.mx.hostcenter.com.

The message from the Hostcenter Server ist: (reason: 554 Denied)

What I have found out since is: The Recipient uses the Hostcenter's anti-spam 
Solution.
This is a 'blackbox solution' operated abroad, the Hostcenter Techs have no 
access to logfiles and there is not tech support abroad for that solution 
which could look into logs to tell what goes wrong.

It is impossible to find out why an email was rejected.

So the only thing I can tell our customers is: It's not working because the 
recipient is using a anti spam software which does not like your emails. 
Please communicate via fax or letter, just accept that email is not working 
and that we cannot fix it because the problem is at 
mail-fwd.mx.hostcenter.com and not our mailserver.

But the customers of course keep blaming us, because our server is 'not able 
to send mails to mail-fwd.mx.hostcenter.com'.

I wonder, are we the only ISP which gets this many complaints about emails not 
being accepted by mail-fwd.mx.hostcenter.com or are others also affected?

Mit freundlichen GrĂ¼ssen

Benoit Panizzon
