Postfix & MS-outlook
 

I have question about setting Outlook to sendmail. First, my Linux server which has postfix install on it. I can send & receive mail at this Linux box. I then try to setup Outlook on my windows computer to send and receive mail through this server. When I setup pop3, I can login, receive mail but can not send mail out. :(
Do I need to do anything with file main.cf to make it work? Or I have to do something else?
Please advise

Thanks

You shouldn't need to do anything special. As long as postfix is running, it will be listening for incoming SMTP mail.

Try sending a mail from Outlook and looking at the log files for postfix. On my Mandrake system they are /var/log/mail/info, errors and warnings. They might give you a clue as to what is happening.

It say: ...
Recipient address rejected: Relay access denied;
.....................

What did I do wrong?

In the /etc/postfix/main.cf file, check the "mydestination" parameter.

Try setting it to $myhostname, localhost.$mydomain, $mydomain
Also check that myhostname and mydomain are correctly set.

Check that the second comma is in place (between the two $mydomain's).

Now restart postfix and try sending again.
