Preventing SPAM

Dalay

After making a lot of search, I am still unable to find the right way to stop Outgoing Spam from server.
I am aware that this is not directly an OpenVPN issue.
Stilll, I'll be really happy if anyone provides this information.

Blocking spam in precicely which context? I'm sure the spammers have a sizable repertoire of techniques for polluting the air-waves, but a common stop for them is to block the outbound port to mail servers:

/sbin/iptables -A OUTPUT -p tcp --dport 25 -j DROP

if it is your mail server , check your relay rules...

Thanks for Your replies.
It was not the mail server but the SMTP port.
Bebop's iptables rule done the job.
