+* msmtp, message mode and multiple accounts
+
+ As an alternative to running a mail server such as sendmail or
+ postfix just to send email, it is possible to use
+ [msmtp](http://msmtp.sourceforge.net/). This small application will
+ look like /usr/bin/sendmail to a MUA such as emacs message mode, but
+ will just forward the email to an external SMTP server. It's fairly
+ easy to set up and it support several account for using different
+ SMTP servers. The msmtp pages have several examples.
+
+ A typical scenario is that you want to use the company SMTP server
+ for email coming from your company email address, and your personal
+ server for personal email. If msmtp is passed the envelope address
+ on the command line (the -f/--from option) it will automatically
+ pick the matching account. The only trick here seems to be getting
+ emacs to actually pass the envelope from. There are a number of
+ overlapping configuration variables that control this, and it's a
+ little confusion, but setting these three works for me:
+
+ - mail-specify-envelope-from: t
+
+ - message-sendmail-envelope-from: header
+
+ - mail-envelope-from: header
+
+ With that in place, you need a .msmtprc with the accounts configured
+ for the domains you want to send out using specific SMTP servers and
+ the rest will go to the default account.

+* <span id="sync_maildir_flags">how to sync notmuch tags and maildir
+ flags</span>
+
+ There is no built-in support for sunchronizing your notmuch tags
+ with your imap maildir flags (seen, replied, trashed, etc). However
+ there are currently 2 ways in which you can achieve
+ synchronization. In order to sync new notmuch tags to maildir flags,
+ there is a python tool called
+ [notmuchsync](http://spaetz.github.com/notmuchsync/) that allows
+ synchronization in either direction or pruning of deleted files.
+
+ The second solution allows for fast maildir flag to notmuch tag
+ synchronization (and only in that direction) requires patching the
+ notmuch source code. The patch has been posted in this mail
+ *id:1267450136-31749-1-git-send-email-Sebastian@SSpaeth.de* and can
+ be viewed as a [source diff in this git
+ repository](http://github.com/spaetz/notmuch-all-feature/commit/df3b087cefb85e9d16fd17540e348bcb854dd7ee).
+
+* <span id="address_completion">**how to get email address completion**</span>
+ There are 2 solutions. Use "bbdb" which allows you to maintain a mail database and gives you mail address completion with the tab key.
+
+ Alternatively, you use the notmuch database as a mail address book itself. This is how you compile the (3rd party) tool "addrlookup" to give you address completion:
+
+ - you need the addrlookup binary, first of all. Grab http://github.com/spaetz/vala-notmuch/raw/static-sources/src/addrlookup.c and build it with *cc -o addrlookup addrlookup.c `pkg-config --cflags --libs gobject-2.0` -lnotmuch*. That should give you the binary that you can test already.
+
+ - EUDC is integrated into emacs and can be used for tab completion
+ of email addresses. The code I use is here
+ http://gist.github.com/359425. It was announce in [this
+ mail](http://mid.gmane.org/87fx3uflkx.fsf@jhu.edu)
+ (id:87fx3uflkx.fsf@jhu.edu) which contains links to the git
+ repositories which contain the files.
