Courier 3.5 review
Until development ceased, Calypso was a highly respected email client. Rose City Software has now released a free updated version named Courier. This adds much of what Calypso was missing, including colour marker tagging of messages, better SMTP authentication support and an ability to quickly toggle between plain text and HTML views. It’s secure, highly configurable and is speedy in use. The interface has changed little from Calypso, which is a good thing; however, it’s very slow in use, which certainly isn’t. Worthy of evaluation, but we’d wait for Courier 4 before switching.
