with outlook I've a problem: I can send mail without set "smtp-auth" in outlook! Why? I followed the perfect setup... If the mail of the account (in outlook) doesn't exist in the server, I can't send mail, if the mail of the account (in outlook) exist I cand send messages... Courier work fine in pop3 and pop3s... Can you help me?
It is normal that you can send emails to accounts that where on your server. If this wont be possible, your server would not be able to receive mail for you email accounts.
I try to send mail out of the server without use smtp-auth. example: from [email protected] a try to send a mail to [email protected] without use smtp-auth. I can send the mail... It arrive...
No, only smtp. There are three cases when you can send emails without authentication: 1) You're sending from a system that has an IP address that is within the mynetorks range in /etc/postfix/main.cf. 2) You're sending from the server itself (e.g. with a webmail program). 3) You're sending to a recipient who is on the server. In all other cases you need authentication.
In mynetworks there is "127.0.0.0/8" only. The server is out of my home... I try to send a message from a mail that is in the server (with outlook without smtp-auth) to a mail that is on gmail (for example). The mail start and arrive...
Sorry I'M VERY VERY STUPID.... I DON'T KNOW WHY, BUT WHEN I TRIED TO SEND A MAIL OUT OF THE SERVER THE SMTP-AUTH WAS SET. WHEN I TRIED TO SEND A MAIL WITHOUT SMTP-AUTH, I'VE TRIED WITH "CHECK MAIL CONFIGURATION PARAMETERS" (of outlook): I TRIED TO SEND A MAIL FROM MY SELF TO MY SELF... SORRY...
