SMTP open relay problem
Posted: Fri Dec 28, 2007 11:30 am
Hello,
I've got a scalix server runing for a long time, and i've detected a strange situation.
i can telnet to the smtp port (25) and send mail to my own mail domain without authenticating...
if i try any other domain fails (which is what i want)
but i want to force authentication also for my own mail domain...
EXAMPLE:
220 "My Mail Domain - SMTPd"
helo xpto.com
250 mail.mymaildomain.com Hello [84.91.76.77], pl
mail from: re@xpto.com
250 re@xpto.pt... Sender ok
rcpt to: xpto@gmail.com
550 Denied due to spam list
rcpt to: xpto@mymaildomain.com
550 5.1.1 xpto@mymaildomain.com... User unknown
rcpt to: testuser@mymaildomain.com
250 2.1.5 testuser@mymaildomain.com... Recipient ok
my smtpd.cfg:
GREETING="My Mail Domain - SMTPd"
EXTENSIONS=AUTH,DSN,8BITMIME
SMTPFILTER=TRUE
RELAY accept 127.0.0.1
RELAY accept .mymaildomain.com
