Hi,
I have been succesfully running postfix on Sarge as a local mailserver
relaying all outbound mail (from multiple internal accounts) to my ISP.
However my ISP has just decided to require SMTP authentication.
I have set up SASL following the postfix documentation and the
authentication phase succeeds, *however* postfix does not include the
authenticated sender address in the AUTH section of the MAIL FROM
message and my ISP is still refusing the message :((
...patch snipped ...
This works BUT only for a single user since the postfix version in
sarge (2.1.5) doesn't implement the
smtp_sender_dependent_authentication option and my ISP actually wants
the correct password for each email address (not just a single one for
all addresses associated with the account.
Are you sure about that? I tested a couple of weeks ago, and mail from
me went through without trouble. If you are right, handling bounces for
your users (and mine) might become tedious. Do you have a solution?
Anyway, to get around the whole thing you can set smarthost like so, to
use the gateway for commercial customers:
relayhost = [smtp.tele2bedrift.no]
Caveat: I talked to their support-staff before setting this up, so they
may have added my IP to some "allowed senders" list. I don't think so
though.
The gateway for commercial customers does not require authentication
when you are coming from inside their network. They run spamassassin on
everything going through there, so they have managed to keep that server
off most rbls.
