Email/member Cleaner

[gdws]

Is there any module for invisionboard which can scan all accounts email addresses, again mx records and reverse dns info and if invalid, move them to a specific group?

my forum i have over 19k members and when i send out emails i get about 3k bounces.

i have a similar problem, but i can track them using regex in mysql...maybe you could make a shell script

Valid mx record and reverse dns doesn't really make it a valid email.
lasjeoifualsjdlfkjasdf@gmail.com would then be considered valid.

There are email validators out there that connects to the said server and queries to see if it's a good email address. First one I found on google was:

Not free through. If you can find some sort of script (or make it), you could run it yourself though. The concept isn't too complicated...
