I maintain various mail servers for ISP's and private companies

blacklist.
We don't know if you are using SAV, TMDA or are just a clueless admin
who bounces after accepting. Seeing as how we get over a million
bounces after accepting from various clueless admins around the globe
you might see how were adverse to any type of sender verification.
You might welcome it but we can't tell the difference. If you're
servers end up on blacklists because of it, don't complain. You made
your own bed and now you have to lay in it.
I wouldn't be on your black list unless you manually added me to it.
My list is all manual. If you have 500 - 2000 rejects a day and you
look like a regular mail server you aren't listed. If you have more than
that or your have over 500 a day for a few days in a row, you are most
likely listed.
I can't tell the difference between idiot admins who bounce after
accepting and (I want to say idiot here, but I won't, opps, I did)
admins who use TDMA or SAV.
Same difference to me, you get blocked. My servers are busy enough as
it is (just as an example, one incoming SMTP server out of 4 with one
client has consistent 80 connections per second, an average 500
connections active at any given tine, the majority, over 80%, bounces or
SAV checks). So guess what? I'm going to block those servers until
they smarten up.
Train the million+ dummy admins out there not to accept, then bounce and
SAV might work but until then it will get you blocked.
Just my 0.02.
