Postfix bounces all incoming mail. No local delivery.

To me it looks like your postconf is missing the "myhostname" and "mydomain" entries, so postfix does not know what is your local domains.

In mine, there's no such placeholders by the way, but the hostname is directly written there. Relevant parts follow:

myhostname = orion.tianet.de
myorigin = /etc/mailname
mydestination = orion.tianet.de, localhost.tianet.de, , localhost
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -a "$EXTENSION" -d $LOGNAME
home_mailbox = Maildir/

Howdy,

Hmm, a few questions for you --

• If you go into System Settings -> Re-Check Config, does everything check out okay?

• In your above example, it's trying to deliver to a user named "support.theclient.com". Is there a user on your system with that name? That is, if you run "id support.theclient.com", do you see a uid and gid for that user, or do you get an error about the user not existing?

Actually, that's enough for the moment... I have some more questions based on the answers to the above :-)

In theory -- your mydestination should be okay. However, Locutus is right that it would normally explicitly list your server's hostname.

The mydestination line is just a list of names for which your server receives deliveries -- adding a name there wouldn't break anything that currently works.

Just as a troubleshooting step, I'd recommend adding "ops01.thesystem.com" to the end of that mydestination line in your main.cf, and restarting Postfix.

I don't think it'll fix it (the error message for that particular problem is usually different), but it's worth a try :-)

Also, having the recipient_canonical_maps set is a non-default... it's possible a setting within those maps could be causing the trouble you're seeing.

You might want to temporarily comment out the line beginning with "recipient_canonical_maps" and restart Postfix, just to verify that things don't spring to life afterwards.

I know this is an old topic, but do you remember what you did for this person

I was originally going to say "I have no idea", but after doing some digging, I dug up an email I sent afterwards explaining what I changed.

In summary:

1. The hostname was a domain (like domain.tld), not a FQDN (like host.domain.tld) -- this isn't true in your case.

2. The domain had a Virtual Server setup for it -- and that Virtual Server had a catchall that was forwarding email elsewhere. That was causing all email to bounce. If your hostname is "ops01.thesystem.com", I'd recommend making sure that there isn't a Virtual Server of the same name. That can cause trouble :-)

3. In /etc/hosts, the server's hostname was listed next to 127.0.0.1. Instead, it should be next to the server's public IP address.

Well, I'm not sure what specifically is causing the trouble.

I notice that your Postfix config has some non-default things in it... you should certainly be able to make various edits and changes to that, many folks do.

But, when seeing the problems you're seeing -- you may want to start whittle things out of there, working your way towards a default Postfix config, to see if something in there is causing the problem you're having.

I'm looking at a new Ubuntu install here, and it looks like your Postfix config has 16 lines in it that a default installation doesn't contain. That may or may not be the actual problem, but it's worth looking into it :-)

Here is what a default setup looks like -- if you were to change the mydestination line, but otherwise use the rest of this as-is... does that work for you?

If so, you could start adding in your changes one at a time until you begin having that problem again.

Hey, that's great, I'm glad you figured it out!

Thanks for the update.

Have a good weekend!
