I have just installed a SBS2008.
Now several senders complains that their mails is being rejected as spam.
(part of mail from senders receive from administrator)
> #5.0.0 X-Postfix; host XX.XX.XX.XX[xx.xx.xx.xx] said: 550 5.7.1 Message rejected as spam by Content Filtering. (in reply to end of DATA command)>
Can anyone tell me how to fix this?
