Limits worth knowing in Horde

You install and maintain it yourself; it is a client and groupware layer that needs your own mail server.
Support is community-based; the project points to B1 Systems for paid hosting and support.
The project blog describes recent releases (Horde 6, IMP 7) with rough edges and a security fix shortly after launch.
It is community-maintained with no vendor behind it, so there is no service-level guarantee.

How this page was made

Where any alternative here is in our top three email apps, the best for most people is the highest placed of them: the top three weigh who each tool suits as well as its grades. Otherwise the page names the highest-graded alternative in the same category as Horde, the one its listing names first winning a tie. The best free one is the highest-graded alternative that is free or has a free plan (a free trial does not count), with its catch quoted from its listing where the listing states a short one. The GPA is the average of our five grades for each tool.
