Dear Viktor,
Thanks a lot for your very helpful reply!
I implemented all the changes you suggested and now it works. My late
reply is due to the fact that I needed to wait for another mail from
outlook.com to see if everything works.
What I find a little odd about outlook.com's behavior is that

No. Thats whats SPF is designed to prevent. Else every phisher would claim
they "forwarded" the email, to bypass the whole SPF security system.
There is two options here, except for disabling forwarding altogether and
require gmail owners to fetch instead:
Either, you replace the MAIL FROM an
Hi Alex,
A mail server that I operate had similar issues several years ago. Our
solution was to stop users from forwarding, and make them use gmail's POP3
support for fetching mail. Whenever a new user gets their account set up,
we ask them if they want to use our webmail interface or gmail, and h
Hi,
I have a postfix-2.10.5 server on fedora, and have several users that
forward their mail through to gmail. This is apparently enough to
break SPF and make gmail think I'm the originator of the email,
instead of the actual sender. Consequently, gmail considers it spam
and moves it to a spam fol

Hello,
I am trying to build postfix with TLS support.
I have Debian, with the openssl package installed (as well as libssl-dev).
Reading the instructions here:
http://www.postfix.org/TLS_README.html#build_tls
It states "Do not use Gnu TLS".
The only libssl.so file I can find is:
/usr/lib/x86_64
