Multiple domains on postfix + postgresql mail server[SOLVED]

I'm currently running a mailserver that has the list of domains and mailboxes in a sql db. The first domain, example.com works fine in sending and receiving email. I set the next domain up, example.net. After getting example.net all setup with postfixadmin and sending an email to user@example.net from my gmail account I get an error email back from the gmail daemon saying:

I tried to telnet through port 25 to example.net and got the following...

It looks like the problem is not with your mail server. Nothing in your logs and Gmail bounce. You sure DNS is fine for example.net?

.:chrome:.

you must create a table, in your database, for all your local domains.
then you have to add, in your postfix configuration, for a query for local domains:

If nothing is appearing in your mail logs then how can it be your mail server that has the problem? If Gmail has tried to send it then Postfix would log the rejection.

Tried messing with it today and still didn't have any luck. If it helps anyone, I followed this guide to get my first domain working: http://gentoo-wiki.com/HOWTO_Email:_A_Complete_Virtual_System

Does Postfix normally write to your logs?

Do you see any sign of this in your logs?

If the answers are No and No then why do you think this is your mail server at fault?

Postfix writes all the standard activities to the syslog.

POP3 and all that are nothing to do with Postfix.

If Postfix was incorrectly configured for example.net then it would refuse email for example.net or bounce email for example.net or accept it and stick it in a deferred queue if there was some other funky config.

Your logs show NOTHING.

The other MTA is not even trying your server.

If the other MTA did try your server it would be in your logs.

It cannot be your mail server if you have nothing in your logs. It does not mean that Postfix does not know how to log for just that domain. There is nothing happening at your mail server.

If you can send an email from another SMTP server you have visibility of then do that and watch those logs to see why it fails.

Don't worry about me. I could have just cruised on by after all :-)

telnet example.net 25 proves little regarding suitable DNS set up for an MTA. From the point of view of a mail server it only cares about MX records. You could have a domain and point that to an IP but you'll get no email.

Stick your domain on this site http://www.dnsreport.com/ and check it. Pay particular attention to the MX section.

Hey sorry for the long time before a reply back. I've been busy at work and school x_X.

Alright, thanks to checking the DNS information, I found that the spam server was not redirecting to the mail server afterwards. After fixing this I sent out another email I got another relay access denied, but this time from the spam server. I set mynetworks_style to subnet and now the mail server accepts the connection from the spam server. Now the .maildir is not being created for the user. I'm reading the system log and it shows the email coming in from the spam server but it never creates /home/vmail/example.net/USERNAME/.maildir

I read throught the system log but I am finding nothing useful to my problem of why the .maildir isn't being created.

Here is my system log for the email that was sent to rob@example.net...

spamphibian.example.net is the spam server
thingee@gmail.com is my current email address that is sending an email to rob@example.net
rob@example.net is the email address that I am trying to send an email to

Welcome back :-)

Looks like your server does not think it is the final destination for rob@example.net. So it then tries to pass the message to spam gateway but realises this would just create a loop and fails with the error message about routing loop detected.

Virtual user must not be correctly set up.

This final bit tells it all.

Yup you're right. I forgot to put a trailing slash on the user rob's .maildir location row in the database. Instantly that fixed the problem, thanks again!.
