All e-mail sent from his computer is marked as SPAM. Even when sending it to another domain on the same directadmin server. See the message below:
Spam detection software, running on the system "webserver.mydomain.com", has identified this incoming email as possible spam. The original message has been attached to this so you can view it (if it isn't spam) or label similar future email. If you have any questions, see the administrator of that system for details.

Shouldn’t he be able to use my own directadmin server as a SMTP server? so mail.hisdomain.com ? Why is it complaining that his dynamic ip causing the problem? Shouldn’t it be sent and relayed by my directadmin ip (and not 188.8.131.52)?
I use my provider smtp server for my mail domains on this directadmin server so have never noticed this problem.
Here is a screenshot of the settings and the domain, please dont quote the domain name as it will appear in google results (just use a substitute.. thanks)
Anybody know what’s going on? It seems the problem only happends from his outlook client and not from the webmail (roundcube). Is there no other option but to use his own smtp server from his ISP?
