Open-source IMAP clients
September 10 2011
For my work, I had to find a good open-source IMAP client that runs
in Windows. Here are some notes I took during my research:
- Claws mail: Unstable code base;
frequent crashes. Puts a large number of half-complete draft messages
in one's Gmail "sent" folder while composing a message. Does not support IMAP
servers without APPEND support.
- Sylpheed: Windows port
does not have built-in spellchecker.
- Mahogany: Dead codebase
(no updates since 2006/2008). No apparent support for IMAP-over-SSL.
- Mulberry mail: No apparent
support for alternate ports for IMAP-over-SSL and SMTP-over-SSL.
- Alpine: No apparent
support for IMAP-over-SSL.
Not very suitable for writing traditional 80-column fixed-width
text emails. Besides that, excellent (Automatic email configuration,
IMAP-over-SSL, supports IMAP servers w/o APPEND, etc.)
- KMail: Did not try
(Installing an entire desktop environment just to have an email client
Thunderbird is the best email client to use in modern work environments
where HTML-formatted email is the norm. While it does have support for
non-HTML mail, this support is limited.
Claws Mail will become an excellent email client for legacy 80-column
monospace text email when and if the bugs are fixed.
Sylpheed may become a good email client, but it could really use Windows
spell checking support.
I have made a minor tweak to the CSS: With some video drivers, the CSS
elements are placed one pixel off left or right in Internet Explorer 9.
This in mind, I have given all of the CSS layers used for the "dissolve
border" background colors so the page still looks good when this IE9 bug
