Marius,
Even that isn't enough; if the Author ('From:') and Sender (SMTP
'Mail From') don't match, the resulting mail will wind up often
being filed as 'spam' by Gmail and others. I have this problem
when sending mail as "From: brian(a)ampr.org" quite often.
Google says it's my fault; I say Google has its collective head up
its ass in marking a valid email as spam. Their official word is
"Don't act like the bad guys" and you won't have problems. Never
mind that it's 100% RFC-compliant, they say it's bad guy behaviour.

It think there is a small issue on the mailing part to
the coordinator.
The mail system sends the message as originating from the sender. This is actually wrong
and will lead to delivery failures like:
<marius(a)yo2loj.ro>ro>: host mail.yo2loj.ro[89.33.44.100] said: 554 5.7.1
<marius(a)yo2loj.ro>ro>: Sender address rejected: Sending from this domain
outside the internal network is prohibited! (in reply to MAIL FROM command)
So please use 'MAIL FROM' with something like mailer(a)portal.ampr.org (preferably
with a valid DNS and MX entry) and use the originator mail in the 'From:' field
(this will make that address show as the originator).
Marius, YO2LOJ
