The emphasis these days seems to be free email over paid for email, can you really earn from banner ads and do users really want advertising everytime they collect their mail?
I personally don't, i have a personal email account with mailbank.com.
My research has shown that if have a good domain name relevent to users interests and you offer pop3 as well as webmail and wap and no advertising, then they will pay.

Anyone else have experience or thoughts on this as all software solution for email seemed to based around the idea of free mail, GMail included.
