Hi,

After following the guidelines set out in http://flurdy.com/docs/postfix I get an error saying "Invalid Zone Type: Local"

Can anyone help me out as I can't seem to find the solution to the problem anywhere online?

Cheers

I am pretty far along in the guide, at the testing stage and i am having undeliverable mail. I am using postfix to smtp relay to an exchange server, i telnet into the device and am able to ehlo, mail from, rcpt to, and data, just fine and it queues up my mail message. But at the point watching the exchange server the email never nor does my system connect to the server with the email. i put my exchange server under relayhost in the main.cf and also changed 127.0.0.1 for mynetworks to my external ip's network.

Any idea whats wrong or how to debug the postfix step by step.

SOLVED: I had an error in authmysqlrc .. now I just need to figure out how I can send mail to the outsideworld. If I send mail to an address in my domain it works fine.. but If I try and send mail to say my gmail account the server denies the relay request.

sorry for teh double posting... didn't realize there was a dapper thread

anways..

I am running into a small problem. Whenever I try to auth to check mail the login fails. I have verified that the password that is being send and the password stored in the mysql database match, so I can't figure out why it is failing.

However I have noticed the following in my logs

Jun 30 07:24:52 zues imaplogin: Connection, ip=[::ffff:xxx.xxx.xxx.xxx]
Jun 30 07:24:52 zues imaplogin: LOGIN: DEBUG: ip=[::ffff:xxx.xxx.xxx.xxx], command=CAPABILITY
Jun 30 07:24:53 zues imaplogin: LOGIN: DEBUG: ip=[::ffff:xxx.xxx.xxx.xxx], command=LOGIN
Jun 30 07:24:53 zues imaplogin: LOGIN: DEBUG: ip=[::ffff:xxx.xxx.xxx.xxx], username=user@domain
Jun 30 07:24:53 zues imaplogin: LOGIN: DEBUG: ip=[::ffff:xxx.xxx.xxx.xxx], password=cleartextpass
Jun 30 07:24:53 zues imaplogin: authdaemon: starting client module
Jun 30 07:24:53 zues imaplogin: authdaemon: TEMPFAIL - no more modules will be tried
Jun 30 07:24:58 zues imaplogin: LOGIN FAILED, ip=[::ffff:xxx.xxx.xxx.xxx]

stripped IP's and acutal domains/passwords/users.. any ideas what is wrong with my setup?
