Some data about the mail that hit my personal mailserver since mid-June:
|Reject 450 Invalid Domain||16232||46%|
|Reject 554 lists.dsbl.org||434||1%|
|Reject 554 relays.ordb.org||5||0%|
|Reject 554 relays.visi.com||8||0%|
|Reject 554 sbl-xbl.spamaus.org||5414||16%|
That’s right, 63% of the mail that hits my MTA is rejected straight away because it was either sent from an invalid domain or the sender’s IP was in a blacklist. Pretty impressive. Even after that, I still get several hundred pieces of spam a day that Spamassassin catches.
