Suddenly postfix is refusing to relay email

    This morning, postfix is refusing to send email to external address. I can send to local addresses, but nowhere external:

    12/06/2009, 12:19:03: SEND - Message has not been sent. Server reply - 4.7.1 <recipient@address.com>: Relay access denied

    It was fine yesterday, and nothing has changed, except maybe an apt-get upgrade.

    I'm not sure the master.cf is right, though. I've had this problem with sending via port 587 and tried to work out why, but now is is not working on port 25.

    Have you asked your access provider if they are blocking any ports? Did you cjeck if your IP got blacklisted?

    It isn't a problem sending emails on: the ispconfig server's instance of postfix is refusing the connection from the email client. Some users get asked to enter their smtp authentication password, but that is rejected - even though it is correct.

    Mails addressed to domains hosted on the server are accepted OK.

    I wonder if an apt-get upgrade changed some sasl library or similar, becasue that is the only thing that changed at the time the problem started.

    You should go trough the mail part of the perfect setup guide again and check if all sasl settings are correct.

    I followed the perfect setup when I set the machine up about three or four years ago, and it was working fine until yesterday.

    I'm worried that if I mess with a setup that was working, I may break something else.

    Is there anything in particular that might be worth checking?

    [Later:]

    Fixed it!

    Although apt-get had claimed to upgrade some libraries, using "aptitude safe-upgrade" found some installed but not configured packages. It fixed them for me, and now all is working just fine.

    Thanks for the help.
