Well, I don't see any "strange thing" with rkhunter...

That's a little weird!

I Start Postix and:

SMTP helo=<mvx-201-76-189-2.mundivox.com>
Jan 17 13:40:25 vp7 postfix/smtpd[21407]: NOQUEUE: reject: RCPT from n: 554 5.7.1 <aogr@kimo.com.tw>: Relay access denied; from=<ideesujmslqf@googlegroups.com> to=<aogr@kimo.com.tw> proto=SMTP helo=
Jan 17 13:40:25 vp7 postfix/smtpd[21396]: NOQUEUE: reject: RCPT from ]: 554 5.7.1 <g6wu0djo6@yahoo.com.tw>: Relay access denied; from=<tuqsg@ms54.hinet.net> to=<g6wu0djo6@yahoo.com.tw> proto=SMTP helo=<187.115.194.22.static.gvt.net.br>

I don't even know what e-mail accounts are these....
Hi,



silenceti you know the difference between sent and rejected? Can you post your mail.log?

Cheers

HI,

I'm thinking to change the port 25 to other one, there is a way to change to other port and block 25 ?

Thanks.

If you do that, remote mail servers won't be able to connect to your mail server.

If noone needs to connect to the mailserver from external IP's, then close port 25 in the firewall. If you want to change or add a additional listen port, then edit postfix master.cf

I've tried to add an additional port and block port 25 in my server.... i can add for example 27 port, but i can't connect to it...

This problem is getting me mad!

"from=<cszznjowtiak@yahoo.com.tw> to=<club6689@yahoo.com.tw> proto=SMTP helo=<213-224-29-62.iFiber.telenet-ops.be>

NOQUEUE: reject: RCPT from unknown[myIP]: 451 4.3.5 <unknown[myIP]>: Client host rejected: Server configuration error; from=<rxofq@aol.com> to=<sogo@yahoo.com.tw> proto=SMTP helo=<static-200-105-212-110.acelerate.net> "
