"Excellent default e-mail program for Windows."
Comprehensive; secure; easy to use for News, POP and IMAP accounts; clean set up of accounts; installs easily; Good GUI, with themes available; handles add-ons; updated regularly and automatically by Mozilla, and the app is Free.
Spam filtering, though adequate, is limited. Recommend using 'Spamihilator' with TB for comprehensive filtration.
Nice app, give it a shot.
