YAY looks like im protected I found some software on the internet "TopMail" which can send anyomouse email through a selected SMTP server And it just gave me two errors when using my SMTP server Recpient Address Rejected Relay Denied Looks like im safe
You might also consider to give http://www.abuse.net/relay.html a try; it checks multiple ways of sending over an open relay.
Thanks looks very usefull my router broke so its mucked up my servers connection ill test it as soon as i can
lol, i just read my mail.log quite funny, damn unauthorized bots / users: Code: Feb 15 02:52:50 srv1 postfix/postfix-script: starting the Postfix mail system Feb 15 02:52:50 srv1 postfix/master[2875]: daemon started -- version 2.1.5 Feb 15 04:20:26 srv1 postfix/smtpd[3048]: connect from 61-216-82-69.dynamic.hine t.net[61.216.82.69] Feb 15 04:20:27 srv1 postfix/smtpd[3048]: NOQUEUE: reject: RCPT from 61-216-82-6 9.dynamic.hinet.net[61.216.82.69]: 554 <[email protected]>: Relay access denied ; from=<[email protected]> to=<[email protected]> proto=SMTP helo=<***.** .***.**> Feb 15 04:20:28 srv1 postfix/smtpd[3048]: lost connection after RCPT from 61-216 -82-69.dynamic.hinet.net[61.216.82.69] Feb 15 04:20:28 srv1 postfix/smtpd[3048]: disconnect from 61-216-82-69.dynamic.h inet.net[61.216.82.69] and then again: Code: Feb 15 10:42:07 srv1 postfix/smtpd[6624]: connect from unknown[61.42.190.245] Feb 15 10:42:08 srv1 postfix/smtpd[6624]: NOQUEUE: reject: RCPT from unknown[61. 42.190.245]: 554 <[email protected]>: Relay access denied; from=<mail@yourdomain .com> to=<[email protected]> proto=SMTP helo=<***.**.***.**> Feb 15 10:42:08 srv1 postfix/smtpd[6624]: lost connection after RCPT from unknow n[61.42.190.245] Feb 15 10:42:08 srv1 postfix/smtpd[6624]: disconnect from unknown[61.42.190.245] I assume this is the work of a spam bot as i dont know anyone who can open a telnet connection on an smtp server and send an email through it all within 1 second.
correction on that last post of mine, i did a bit of reading on and some minor testing of my own and found that if you send an email via a gui mail client such as microsoft outlook, or some other spaming software, the log files would read the same.... but who would know bout my server, must be an asian script kiddy trying to spam / flood / bomb someones email and failing misserably, i think they moved on to some lower hanging fruit...
