= Mail Clients =

Since imip-agent is integrated with mail infrastructure defined by Internet
standards, users can use any mail program that is capable of sending and
receiving standards-based mail. However, it is recommended that
[[http://tools.ietf.org/html/rfc2045|MIME]]-capable mail programs are used
in order to properly present messages produced by imip-agent. Since the MIME
standards have been in existence since the 1990s, most commonly-used mail
programs should work with imip-agent with few difficulties.

Meanwhile, mail clients that can understand and present calendar data are
less common. The following Free Software programs have been tested with
imip-agent:

 * Supports scheduling including methods like `COUNTER`
 * Supports recurring events
 * Seems to support free/busy exchange over e-mail (although not
 transparently) and over HTTP
 * Seems to require numerous libraries and KDE components, including the
 somewhat unpolished [[WikiPedia:Akonadi]] system

''Also known as Icedove (and Iceowl) in Debian''
||
 * Supports basic scheduling
 * Supports recurring events but has deficiencies with `RDATE` and `PERIOD`
 datetimes, causing variations from the basic event duration to be discarded
 * Does not support the `COUNTER` scheduling method
 * Does not support free/busy exchange over e-mail, but can be made to
 fetch free/busy data over HTTP

See [[http://tools.ietf.org/html/rfc5546#section-3.2.7|RFC 5546 section 3.2.7]]
for details of the `COUNTER` scheduling method.
