I have this problem:
I need to send messages between users of the same domain.
When I send a message from 1 to the other, if I send it from webpanel, no problems, if I send it throug outlook express, the message goes in the spam folder.
Why? How can I prevent this problem?
This problem occurs for all domains I have on the server, while receiving external mail is ok.
For a better explanation of the problem here is the header of the mail flagged (uncorrectly) as SPAM:
X-Virus-Scanned: amavisd-new at
X-Spam-Status: Yes, score=8.444 tagged_above=-10 required=6.6
tests=[AWL=-0.626, BAYES_99=3.5, DYN_RDNS_SHORT_HELO_HTML=0.499,
FH_DATE_PAST_20XX=3.188, HTML_MESSAGE=0.001, RCVD_IN_PBL=0.905,
Thanks in advance for your help
