outgoing SMTP conversation is causing failure.

the outgoing smtp mail pre-amble does NOT seem to include the full host name in the helo - i noticed this as i have recently had to update my spam protection and now require full compliency with some RFC's to try and reduce spam.

your smtp implimentation only puts the host name in the helo command.. i think the RFC states that your HELO should post a fully-qualified hostname;

ie (from my postfix log)

RCPT from smtp.drone.com[132.219.59.188]: 504 <mailserver>: Helo command rejected: need fully-qualified hostname

my postfix will now not accept this (without my intervention) as it expects

RCPT from smtp.drone.com[132.219.59.188]: 504 <mailserver.drone.com>:

which gives the fully-qualified hostname in the helo... i can easily force my postfix implimentation to accept mail from this server but would prefer that i do not have to make exceptions with the config just to get servicedesk mail to work.
