Since I got Zen and the other spam stuff working things went fine until one of our road workers tried to send his email from his laptop which is hooked up on a cheap ISP. This ISP happens to be fully in Zen and he can not send mails using our mail server. He has to log in using IMAP/TLS to send the mails. Is there a way ( inside the recipient restrictions ) to allow mails only from a domain if send by a logged in user? Currently I use a recipient access map to whitelist the domain but this works only until spammers start to send mails with faked domains ( aka claiming to be from this domain but obviously are not since they never authed ). SASL is not an option since it refuses to work ( either crashes or fails to start ).
