I have several things like printers and applications that send email to
a
local linux host running postfix, and I need to get that postfix
instance to
forward all of its email to the Office365.com Exchange server via an
authenticated connection. I have an account that we have used for
system
email previously. It's set up as a normal email user.
I have configured postfix so that it will not deliver any mail locally.
I have set the relayhost to
[smtp.office365.com]:587
I have created a smtp_sasl_passwd file that has the following contents
(redacted where necessary)
[smtp.office365.com]:587 kem...@mydomain.com:PASSWORD
This connects just fine, and rewrites the mail sender when I send email
from
the local postfix host.
I have added the following lines to main.cf to try and get mail from
other
hosts to forward:
sender_canonical_classes = envelope_sender,header_sender
sender_canonical_maps = regexp:/etc/postfix/sender_canonical_maps
the sender_canonical_maps looks like this:
/.+/ kem...@mydomain.com
and I have remembered to run postmap on all of the mapping file I have
tried
over the last week or so of trying this.
but for some reason, no email from any other host or device ever gets
through.
Have you read http://www.postfix.org/ADDRESS_REWRITING_README.html ?
For better help show logs of one message that passes through your
system.
If someone has a working example of a main.cf that is configured to
relay
mail from local systems and devices to office365.com through an
authenticated connection, I would really love to see it. I'm tired of
banging my head on the wall.
Below is my postconf -n output. I have tried several permutations on
this,
so just because you don't see something obvious in that info, believe
me, I
probably tried it.
At any rate, anything I tried failed, so I'm ready to try out all
suggestions.

Take a look at the documentation for sender_canonical_maps

canonical_maps http://www.postfix.org/postconf.5.html#canonical_maps
I suspect you probably need to set local_header_rewrite_clients
http://www.postfix.org/postconf.5.html#local_header_rewrite_clients for
your rewriting of mails from remote hosts to be made.
