"Very good, simple mail client."
T-Bird is easy to set up and use (with an exception noted below). There are a pretty good number of features and mail-handling tools and options. Unlike some free POP clients, it has its own spell-checker. Available extensions can add some functions.
Some are critical of Thunderbird for having no calendar or MS Exchange capabilities, but I think that misses the point. I use Thunderbird because I don't need those features, and prefer something smaller and more streamlined.
Importing account and server information from Outlook resulted in incomplete and incorrect port and security settings that have to be changed in order for the program to work. That could confuse novices.
