I've installed notmuch on my OS X computer and it seems to work fine. I can search, filter, tag, etc. mail successfully. However, when notmuch is loaded, sending mail doesn't work correctly any more. The headers I see after C-x m are: ------------------------------------------------------------- From: /bin/bash: notmuch: command not found </bin/bash: notmuch: command not found> To: Subject: User-Agent: Notmuch/unknown (http://notmuchmail.org) Emacs/23.4.1 (x86_64-apple-darwin) Fcc: /bin/bash: notmuch: command not found/sent --text follows this line-- -------------------------------------------------------- If I comment out the "(require 'notmuch)" line in my .emacs, the "From" line is populated correctly and the "Fcc" line is omitted, which I think is the normal behavior. It looks like there's a problem with the path. But notmuch seems to be on the path since all the other notmuch operations work just fine. notmuch is installed in /usr/local/bin and I have: (add-to-list 'exec-path "/usr/local/bin") in my .emacs file, which I think is one of the recommended ways to set the path on OS X. I poked around email archive and thought that setting notmuch-fcc-dirs might help. I tried setting it, and it didn't seem to have any effect, as the behavior was the same. I'm using notmuch compiled from source on 7/3/2012, OS X 10.6.8, and Emacs.App 23.4.1. I have a very similar setup at work, which works fine, so I'm perplexed about what is wrong here.
