Very recently, I tried using a combination of nail(1), and calendar(1) on OpenBSD as an email and calendaring combination for home use. "nail" is provided by the OpenBSD s-nail package and provides an extended POSIX mailx style environment. calendar(1) is part of the base OpenBSD distribution.
It worked far better than expected. The only thing missed was age calculations for birthdays. I never figured that out. Using the Emacs Diary provided that sort of thing though.
I've since moved to KDE Kontact for mail/calendaring. It works more smoothly if you do a lot of calendar sharing with others, but I could see going back to nail(1)/calendar(1) if Kontact disappoints.
