I'm currently using Squirrelmail which I've been using for years. It works but I'm looking for something modern that my users will really like. Looking for suggestions. What is best for running on a Linux server?
We have both Squirrelmail and roundcube installed. But I personally prefer roundcube. Roundcube has a much more attractive interface in my opinion. They both operate very well however.
I use Horde, Squirrelmail and RoundCube frequently as necessary. Out of those 3 which I have experience with, I can definitely say RoundCube is my favourite for its excellent design and ease-of-use.
No doubt, RoundCube is a nice webmail application and its popular because of its interface. I personally use Squirrel mail as its faster and there are hundreds of squirrel mail skins available that you can install to give a nice look to squirrel mail.
Another vote for RoundCube. I use it for e-mailing interested volunteers, have updates and everything else. Its a real help, and it doesn't have to refresh frames unlike SquirrelMail does.
Squirrelmail, RoundCube or Horde these web mail applications are quit similar to one another. If you are looking for change you should opt Zimbra email hosting service.
