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@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. - Brian

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@yo2loj.ro: host mail.yo2loj.ro[89.33.44.100] said: 554 5.7.1 marius@yo2loj.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@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).
