Is Squirrelmail the best webmail choice?

[Jonathan Horne]

ive used squirrelmail for quite a while, and i just want to make sure i
have my mind as open as possible here.  are there any other choices for
webmail that are about as easy as SM to configure, but offer a better user
interface or experience?

ive heard of horde, but ive not seen it since early 2000 or so, and even
then, when i tried to set it up, it was a complete and total failure.

so, any other recommendations for webmail besides squirrelmail?

thanks,
Jonathan Horne
