[aqoz]

I configured dovecot and postfix according to this article: http://wiki.centos.org/HowTos/postfix

I can send email using webmail but Office Outlook returns an error: Relay access denied

How Can I fix this?

Thanks

This is old solution to handle the user accounts.
If you setup correctly the Outlook, check the syslog file to view to real reason. I think, your PAM authentication is failed.
Try other solutions to authenticate the user:

I found the reason, It's because I don't use SASL and I restricted $mynetworks

Is there anyway to allow all external network in $mynetworks?

Thanks

I suppose you can try throwing your IP into the mynetworks line in /etc/postfix/main.cf. My install just has 127.0.0.1 on that line though I have a complete configuration with SASL.

Thanks, but I can't just restrict it to my IP address. how can I allow all ?

[netfreak]

That would make you an open relay.

Yes, I think I have to find another way

When I configure mail server and SASL, I have to manually enter username and password and go to settings to enbale SASL in order to send mails

is there anyway for outlook to do this automatically>

[aqoz]

any ideas ?

Thanks
