Default Virtual Users And Domains With Postfix, Courier And MySQL (Debian Etch)

V. Users And Domains With Postfix, Courier, MySQL (Deb. Etch) Relay Mails to outside?

Hello,

I followed the specified howto until my aim is reached:

http://howtoforge.com/virtual_users_and_domains_with_postfix_debian_etch

This aim was just the mail-server, without spam/antivirus solution.
So: pages one to three.

I receive mails without any problems, but:
I just can't send mails from outlook or any other client to outside. Outside means: Other domains, not hosted by this server.
If I use squirrelmail for sending mails to other domains, it works without any problems to, like receiving them.
I tried other settings in /etc/pam.d/smtp, I tried postfix not running chrooted (smtpd). But nothing works.
Has anybody suggestions, to remove this error? I DO NOT want an open relay server, but who want this?

I want to authenticate with my credentials, so: email-adress and the password. I don't want pop before smtp, because I'm using imap.

If any logs/configs are required, please let me know, i'll post them.

edit: I tried some things from this page, too:

Can anybody help me?

ps: sorry for my english, I'm native german.

 

Any errors in your mail log?
Did you enable "Server requires authentication" in your email client?

 

Hello,
There were only the same messages, i received with outlook. Just the times, PID, and so on where displayed.

But I got it working know, but don't know how. oO (i'm just reading many stuff about postfix' main.cf and sasl-auth.)

And yes, that was the first i checked.

I'm currently testing the server, not to be an open-relaying one.

Thanks - "Trotzdem Danke "
