I use this:
drop message = HELO doesn't look like a hostname
log_message = Not a hostname
condition = ${if match{$sender_helo_name} \
{\N^[^.].*\.[^.]+$\N} \
{no}{yes} \
}
This means: Drop the HELO unless it contains a . somewhere in the HELO
string, but may not begin or end with a . (imposed minimum length is 3
chars). basically x.x is ok, but .x. is not
