TITLE: Updated Mutt config, multiple accounts

====================================================================


In a long transition away from Google, I made another email account,
on an email system that values privacy and doesn’t sell information
to advertisers. That means that for the moment, I now have two email
accounts. Simultaneously, I thought I would give (Neo)Mutt another
go as my email client, along with Offlineimap (grabbing mail),
notmuch/alot (indexing mail), msmtp (sending email), pass (managing
passwords), vim (writing mail), launchd (scheduling mail sync), and
w3m (parsing HTML email).

Offlineimap

This is my current .offlineimaprc:

    [general]
    accounts = riseup, gmail 
    pythonfile = ~/.offlineimap_pass.py
    fsync = true

    [Account riseup]
    localrepository = riseup-local
    remoterepository = riseup-remote

    [Repository riseup-local]
    type = Maildir
    localfolders = ~/.mail/riseup

    [Repository riseup-remote]
    type = IMAP
    ssl = true 
    sslcacertfile = /usr/local/etc/openssl/cert.pem
    remotehost = mail.riseup.net
    remoteuser = <EMAIL ADDRESS> 
    remotepasseval = GetPassRiseup() 

    [Account gmail]
    localrepository = gmail-local
    remoterepository = gmail-remote

    [Repository gmail-local]
    type = Maildir
    localfolders = ~/.mail/gmail
    nametrans = lambda folder: re.sub('drafts', '[Google Mail].Drafts',
        re.sub('sent', '[Google Mail].Sent Mail',
        re.sub('starred', '[Google Mail].Starred',
        re.sub('trash', '[Google Mail].Bin', folder))))

    [Repository gmail-remote]
    maxconnections = 3
    type = Gmail
    ssl = true
    sslcacertfile = /usr/local/etc/openssl/cert.pem
    remoteuser = <EMAIL ADDRESS> 
    remotepasseval = GetPassGmail()
    realdelete = no
    nametrans = lambda folder: re.sub('.*Drafts$', 'drafts',
        re.sub('.*Sent Mail$', 'sent',
        re.sub('.*Starred$', 'starred',
        re.sub('.*Bin$', 'trash', folder))))

    folderfilter = lambda folder: folder not in [
        '[Google Mail]/Important',
        '[Google Mail]/Spam',
        '[Google Mail]/Chats',
        '[Google Mail]/All Mail',
        ]
    createfolders = True


    postsynchook = notmuch new --quiet

accounts = riseup, gmail tells offlineimap that I have two accounts.

The password for each account, defined by remotepasseval is mapped
to two python functions, found in
pythonfile = ~/.offlineimap_pass.py. See below in the pass section
for what the pythonfile contains.

The rest I think is self explanatory, except for the name
translations. This takes the IMAP name for certain default gmail,
like [Google Mail].Starred, and turns them into names that are easy
to read in the Neomutt sidebar, like starred. It’s also necessary to
change these names back in the remote section of the config file.

Lastly, the postsynhook calls notmuch to recompile it’s database,
checking for new mail. I use notmuch with alot for searching emails
sometimes. At some point it might be nice to see if I can run alot
directly from mutt.

To get offlineimap to run every few minutes, to check if I have new
mail, I use launchd, which is the successor to cron on macOS. I keep
a script in ~/Library/LaunchAgents/ that looks like this:

    <?xml version="1.0" encoding="UTF-8"?>
    <plist version="1.0">
      <dict>
        <key>EnvironmentVariables</key>
        <dict>
          <key>PATH</key>
          <string>/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin</string>
        </dict>
        <key>KeepAlive</key>
        <false/>
        <key>Label</key>
        <string>homebrew.mxcl.offlineimap</string>
        <key>ProgramArguments</key>
        <array>
          <string>/usr/local/opt/offlineimap/bin/offlineimap</string>
          <string>-q</string>
          <string>-u</string>
          <string>basic</string>
        </array>
        <key>StartInterval</key>
        <integer>300</integer>
        <key>RunAtLoad</key>
        <true />
        <key>StandardErrorPath</key>
        <string>/dev/null</string>
        <key>StandardOutPath</key>
        <string>/dev/null</string>
      </dict>
    </plist>

It runs offlineimap in quiet mode (-q, -u basic), every 300 seconds,
and whenever the computer wakes from sleep or is powered on
(RunAtLoad), it also pipes error outputs to /dev/null.

pass

This is the python file I use to call pass to get the passwords for
each of my email accounts. Basically it just runs pass on the
appropriate entry, then takes the output and grabs the appropriate
line:

    #!/usr/bin/env python2

    from subprocess import check_output

    def GetPassGmail():
        return check_output("/usr/local/bin/pass email/gmail", shell=True).splitlines()[0]

    def GetPassRiseup():
        return check_output("/usr/local/bin/pass email/riseup", shell=True).splitlines()[1]

Mutt

Here is my Mutt config, which I keep in ~/.mutt/muttrc:

    # Source other files

    # Always include original message in reply and always reply to sender
    set include = yes
    set fast_reply

    # Ask if unsent message should be kept as postponed
    set postpone = ask-yes

It’s mostly a mash up of things I found online, but these are the
bits I think are interesting.

I use a set of sed manipulations to get the names of mailboxes in
both my gmail and riseup directories to fill the sidebar, using:

    mailboxes `find ~/.mail/* -maxdepth 1 -mindepth 1 | sort | cut -d/ -f5- | sed 's/^/+/' | sed '/notmuch/d' | sed '/INBOX/d' | sed '/riseup/d' | tr '\n' ' '`

I use folder hooks and macros to load separate configs which change
settings for replying to emails depending on which account I want to
use. The extra configs look like this:

    set from = "<EMAIL ADDRESS>"
    set spoolfile = gmail/INBOX
    set postponed = +gmail/drafts
    set record = +gmail/sent

    set sendmail = "/usr/local/bin/msmtp -a gmail"

    macro index D \
        "<delete-message><enter>" \
        "Delete message permanently"

See that set sendmail uses msmtp to send the email, and uses the
account called gmail. This is what my .msmtprc looks like, which
defines those accounts:

    account riseup
    host mail.riseup.net
    port 587
    protocol smtp
    auth on
    tls on
    tls_trust_file /usr/local/etc/openssl/cert.pem
    from <EMAIL ADDRESS> 
    user <EMAIL ADDRESS>
    passwordeval "gpg --quiet --for-your-eyes-only --no-tty --decrypt ~/.password-store/email/riseup.gpg | sed -n 2p"

    account gmail
    host smtp.gmail.com
    port 587
    protocol smtp
    auth on
    tls on
    tls_trust_file /usr/local/etc/openssl/cert.pem 
    from <EMAIL ADDRESS> 
    user <EMAIL ADDRESS>
    passwordeval "gpg --quiet --for-your-eyes-only --no-tty --decrypt ~/.password-store/email/gmail.gpg"

    account default : gmail

The last thing is the mailcap, which uses w3m to parse HTML email as
plain text, and is called into mutt using set mailcap_path:

    text/html;  w3m -dump -o document_charset=%{charset} '%s'; nametemplate=%s.html; copiousoutput
