Also, I like sender verification, but that's me.
i used it for some time, and reluctantly shut it down. blocked a lot
abuse, but too many false positives for my taste.
Could you go into more detail?
Maybe I have others I just don't know about? How many people send
legit e-mail with return addresses which are bogus?
On a related note, for those of you interested, the IADB (ISIPP Accreditation Database) is now up and running, although not publicly announced yet. You can read information about it at:
What is unique about the IADB is that it is designed to list not only IP addresses, but also associated domains *if* the listee is publishing an SPF record, and conversely IADB listees will be able to get a unique "accreditation code" to put into their SPF records.
