I noticed that most e-mail messages sent by infected machines claim in ehlo
or helo that their domain name is the domain name of the e-mail address they
are sending to. For example, if the virus sends a message to
[EMAIL PROTECTED], it claims that the message its domain name is
also targetdomain.tld. Is there a way to reject only such connections that
pretend to be from the targeted domain, but ip is different? (appart from
toggling nodnslookup in courierd config file)
