Well, a few clients come with Cpanel, at least with mine, Horde, Squirrel mail, etc. I am wondering which of those is the best, most reliable. And if there is another email client I should be considering if it is substantially better. Horde and Squirrel have horrendous web interfaces.
I will set it up for my hosting clients myself, thru Cpanel if possible.
I use Outlook or Rackspace webmail. Both state of the art. the 3 above mentioned that come with Cpanel seem dated. I am also not aware of any of the deeper differences/issues with them. My main issue is that I want to offer my clients a true Business Class of email, which is why I farm it out to Rackspace email. I was merely wondering what might be second best in case my client did not want to pony up whatever I charge for the rackspace email. I came across a new email client/server from an ad on here, but forget the name. Looked pretty slick.
