rockeiro Posted January 31, 2007 Share Posted January 31, 2007 I have a question and a suggestion. Question: How many mail admins here have servers that have a feature called "greylisting"? Suggestion: Get it and use it! I maybe receive 3 or 4 spam a week in any particular users mailbox now down from 200-400 a day for more than 2 years now. Quite simply, Spammers can't waste the time retrying 3 or 4 times after receiving a "451 4.7.1 Please try again later" message. Apart from that I have found no effective way to block spam from account abuse from Hotmail or Yahoo. Any effective methods I might not know about (besides spamassassin and bayonesian filters and the like)? Link to comment Share on other sites More sharing options...
