Good evening,
Short version of the question:
If I am rewriting sender addresses using:
/^(.+)@pt\.lu$/ $1+pt.lu:[EMAIL PROTECTED]
/^(.+)+pt.lu:[EMAIL PROTECTED]/ [EMAIL PROTECTED]
How important is the risk to be used as open relay?
Long version of the problem:
The Luxembourgish Internet Provider P&T (pt.lu) is only accepting mail
originating from @pt.lu if the sender is on their ip network (or is
authenticated).
Their policy can be found at:
http://www.pt.lu/webdav/site/portailEPT/groups/DT_redacteurs/public/downloads/Politique%20e-mail.pdf
This makes it impossible to relay mail from [EMAIL PROTECTED] sent to [EMAIL PROTECTED]
back to [EMAIL PROTECTED]
Unfortunately there is no "Debian" or official Postfix version of SRS
(Sender Rewriting Scheme) or RPR (Return Path Rewriting).
That's why I am thinking about using the more risky method of simple
address rewriting like described before.
How important is the risk to be used as open relay?
Thanks for your comments,
Yves
