Dog Days of Summer return

Things have pretty much returned to normal over the weekend — we’re seeing the usual scenario: RBLs such as SORBS, SPAMCOP, FIVETEN and others are netblocking entire IP address ranges from ISPs that have included known spammers in the past…which means they’re continuing to catch non-spamming companies in their nets as well.

There have been a few new reports of open relay problems, while reverse DNS issues have dropped off again…and no new Non Delivery Reports (NDRs) from the major ISPs have popped up so far this week.
