I've configured ISPConfig on Debian Sarge and all is pretty much well. I'd like to allow certain users or domains to do authenticated SMTP from outside the local networks, can this be done? I'm using IMAPS so Pop before SMTP is not an option. thanks, Peter.
This is more a question of your postfix configuration then of ISPConfig. If you configurd postfix for SMTP-Auth as described for example here: http://www.howtoforge.com/perfect_setup_debian_sarge Then you will be able to authenticate against the users created in ISPConfig.
Tim this works but only for local networks - as per the Postfix mynetworks parameter. I'd like to be able to send authenticated mail from any unknown network, and unauthenticated mail from localhost only for webmail. Any idea on how to achieve this? thanks, Peter.
I answered you question already with my post above. What you need is SMTP-Auth with SASL and the setup is described in the link above. I'am not talking about the mynetworks parameter.
