With 127.0.1.1 gmail in /etc/hosts the conversation would go like this: brian@desktop:~$ telnet bendel.debian.org 25 Trying 82.195.75.100... Connected to bendel.debian.org.

Most large ISPs presumably do not see any benefit as they basically ignore an RFC non-compliant helo. The large number of broken mailers about might be a reason. I'm not prepared to risk having mail rejected because the canonical_hostname is not a FQDN known in the DNS. -- Brian.
