question on new joinup emails
Using Jamroom
Kickbox does some extra things to try and determine if it feels the address is good:
- has it seen emails sent to this address before?
- is the domain a valid domain?
- does the domain have valid MX (mail exchanger) records?
- how long has the domain been registered for?
etc.. it then basically gives a "score" to the email address to determine if it thinks it is good.
