Mutt developer resources

Bug tracking system

This trac exists mostly for its bug tracking database: report:3

To add new tickets or comment on tickets, you must be logged in (this is to protect the database from spam). You can register immediately using the link on the menu bar.Note: a valid email address is required (the registration page incorrectly states that it is optional) -- this is to send you a confirmation link. Sorry about that, we'd turn it off if the spammers would let us. Note that bug entries are forwarded to the mutt developer's list, making the email address you register with semi-public.

When reporting new tickets, please make sure that

  • you find a short but meaningful summary
  • describe a procedure for others to reproduce the problem (if possible)
  • select properties carefully, especially the priority, component and type fields
  • add "patch" to the keywords field when you have a proposed solution

See DebugTips for things to do to help diagnose a bug so that we can fix it faster.


Browse the manual for the development version, updated nightly.


The source code is maintained in a Mercurial repository here. You can pull your own copy for hacking with

hg clone

This will clone only the HEAD branch (where mainline development happens. You can omit the #HEAD to clone the entire repository, but then you will need to use another command to check out the latest version into your working directory after the clone:

hg update -C HEAD

Afterwards, hg pull -u should keep you up to date.
