Title: Unwanted IP Addr trying to send mails from my qmail server
Post by: vlinux1 on May 18, 2008, 01:00:31 PM

Hello All,

I am using qmail server (qmailrocks.org). Now the problem is my SMTP is going down frequently.
I allowed only my network in /etc/tcp.smtp but if i check in /var/qmail/qmail-smtp/current log file its showing me diffrent networks ips are trying to send mail from my server.
I am using firewall and my server is behind a firewall and only smtp,pop,imap,http traffic is allowed.

I am confused because different IP Addrs trying to use my SMTP i am using spam and clam both r working well if i check /var/log/maillog

I want to alllow only my IPS to use the SMTP please help me regarding this issue.

Regards,
VJ

its not a matter of very much attention as first if they are able to send the mails or not if your server is not relaying these mails then there is no harm . some time some spammers tries different servers if they are open relay or not.
