I want to develop an emailing site like gmail, yahoo etc.
I have developed a site which works on intranet , I want to make it work on the internet.For this I need a webhost which provides me such a facility but I am not getting it.
I understood one thing that I need a SMTP and POP server for transferring emails.
please help me regrading the issue.
