Check out this link http://www.altn.com/Support/KnowledgeBase/KnowledgeBaseResults/?Number=KBA-01366. Am not an mdaemon expert though, but mail server best practise should be to block open relay by only allowing trusted IPs to relay via your server.

Your server is probably a blind relay. See this http://www.altn.com/Support/KnowledgeBase/KnowledgeBaseResults/?Number=KBA-01366

Hi guys,

I have just been informed by my ISP that our network is spamming :-( Some network engineer tells me that normally, it is the mail server that sends out SPAM. Our server happens t run MDaemon, whose configuration appears kinda cryptic to me. the said engineer tells me that there are settings that need to be applied on MDaemon to prevent it from spamming, but she doesn't remember exactly how that's done. It is on this basis that I am imploring MDaermon gurus [if there's such a thing as that] on the list to kindly throw me a lifeline as guys have started complaining of emails not getting delivered to their intended recipients.


Please help.


Me.
