hello
am using UBUNTU SERVER with postfix

i must say that alot of my mails get rejected due to spam, its not a relay server, it has a static ip which is clean but yet

i just recently got the message : Message rejected; Spam score exceeded 10

how can i make my server spam free or not act as a spam machine ? as this affects my business alot due to international mail servers rejecting my clean mail correspndence with our clients

please advise any steps i should take

Sorry I don't understand your questions what do you ask??

I checked the mail log and noticed so man fake email from my domain trying to send out emails for example: xyz@mydomain.com 1235@mydomain.com and literally thousand such fake ids

Are they causing my mail server to be blocked and being labeled as a spam server??

How can I stop this?? Please help

Yes, that could be the case. Please check if your server is an open relay: http://www.spamhelp.org/shopenrelay/

If it is not, it's possible that spammers abuse a web application on your server - please make sure you have the latest updates installed.
