Invite emails should successfully reach their destination.
Actual behavior
These invites will be filtered or blocked in many cases, because they are sending From: the person doing the invitation. Assuming that person's email is not hosted on the same system as the Sympa lists, sender authentication will fail.
Additional information
The fix (or one possible fix) is extremely simple: just remove the From: line from the mail_tt2/invite.tt2 file. That way, the invite will go out with the default Sympa administrative sender address, code>sympa@lists.domain.org</code (or whatever domain the Sympa server lives in), which will pass sender authentication checks.
