EHLO question
I have notice a increased behavior of incoming connection to our mail
server. They appear to use wrong domain name / IP for the EHLO line.
In the log I see the email server seems to know that it expected
something different, but it allows the connection and excepts the
email.
for example,
$ telnet smtp 25
EHLO foobar.msn.ca
250-mail.scs.ryerson.ca expected "EHLO seraphina.scs.ryerson.ca"
mail then will go through. How do you configure the mail server to
reject connection when EHLO is wrong?
I am running zmailer 2.99.55 with solaris 8.
Thanks,
grace
