"relaying" in this case means handling mail for recipients who aren't in your domain. You probably _do_ want to allow relaying from some hosts, that is, if you send mail out from more than one machine on your local network. So you put mynetworks entries for every network or host who is allowed to send mail via postfix on your server, to third parties. This can include offsite networks or hosts if you wish. Incoming mail addressed to recipients in your domain is allowed, but this isn't considered "relaying". You _don't_ want to allow relaying based on sender domain name. It's too easy to forge "from" address. -- Dan Wilder <[EMAIL PROTECTED]> ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
