hello, i have a web hosting site and i want to give my costumers e-mail software. I allready give squierl mail, round cube etc... But i want something like "yahoo mail", not exactly like yahoo, but i want to give them some functions and me to place banners. On my server is Direct admin. Tell me free or paid software, i just wanna know does that kind of software exist
you wont get anything like the yahoo or gmail interface try roundcube, its better than horde and squirrelmail
I agree if you're going free, you should use Horde or Roundcube, all can be customized. You have to remember Gmail, Yahoo et al spent millions of dollars in development so you'll never get the same functionality for free.
With Google Apps you might be able to achieve your goal: http://www.google.com/a/help/intl/en/partners/index.html
