I notice that rcpthosts on our mail servers can be circumvented by using
the machines ip addressx in the recipient, e.g.:
rcpt to:<crap%spam.com@\<hostname-of-mailhost\>>
553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)
but
rcpt to:<crap%spam.com@[\<ip-address-of-mailhost\>]>
250 ok
Why is this? How do I turn it off?
Cheers.
