| + | Spamd is a software package that put sends unknown mail servers a message of 451: come back later. Correctly configured email servers should come back a few min. later and will be allowed to deliver email. However the majority of spammers(90%+) never come back and so your server doesn't need to process the spam since it is never accepted. | ||
