Under what circumstances is inbound spam rejected upon being sent (and notifying the sender) as opposed to being received then later discarded (after being processed and marked as spam)? If this is unclear, please let me know. Regards, Lewis
ISPConfig's SpamAssassin is invoked by procmail, i.e., the mails are received by Postfix and then passed on to procmail which then calls SpamAssassin. If you want to block mail at the MTA level, take a look here: http://www.howtoforge.com/block_spam_at_mta_level_postfix
Thank you falko as always. Is it possible for Postfix to hold-off accepting the e-mail until it gets an 'ok' from SpamAssassin? It only takes a split-second to scan for spam anyhow, doesn't it? Regards, Lewis
I think you're looking for something like amavisd: http://www.howtoforge.com/amavisd_postfix_debian_ubuntu
