easy removal of bounced e-mails - working!

[fomag]

I have external mass e-mail sending tool but I need a list of good emails extracted from my vbulletin database.

The best solution for me would be a mod:
- adding a user to dedicated group (parameter or fixed) if user email bounced
- setting the flag 'receive emails from administrators' to NO

Then I will extract emails only from 'Registerd users' group or only with flag 'I want to receive emails from administrators' set to YES.
Then I will delete users with bad emails... esp. when they have <5 posts.

The partial solutions for me for now - as it is quite urgent - would be a script which will process input .txt file with bounced email addresses (I will prepare it manually) and set the flag to 'NO'.

I really did detailed research here for a mod handling bounced emails. Some of them didn't work or have different functions then what I need.

If you know sth that works, please give me a tip/link or so. Thank you.

(I also need this for my second froum v3.7.2... but I think I will first do upgrade to 4.2.2...)
