Updated Mutt config, multiple accounts

DATE: 2018-12-15

AUTHOR: John L. Godlee

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:

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
