Best PHP Webmail system to access mail remotely


#1

Which should be the best PHP Webmail system to access my mail remotely to meet such requirements?

  • Outlook Synchronization
  • HTML email composing
  • IMAP support, including IMAP over SSL
  • Live Spell Check

Roundcube Webmail, AfterLogic WebMail, AtMail, SquirrelMail, Which one should be the exact one I am looking for?

Thx
