I'm building my own email verifier/debouncer and wonder if I am missing anything from this checklist
1. [done] Verify that the email address is correctly formed
2. [done] Discard if email address is role based like Sales, Info, admin
3. [done] Verify against a list of disposable address web sites
4. [done] Verify against local blacklist
5. [testing...] If server returns '**Accept-All**' don't use it
6. [done] If the email address times out -add to check_again.txt?
7. If email address is on or is known spam trap, don't use it
8. [done] Add all rejected emails to a blacklist
Currently I have written / implemented all of this, except for the 'Accept-All' and 'known spam trap' part.
Does anyone have any suggestions for something I'm missing?
