I have long experimented with an optimal mail setup. As some readers may be aware there are a lot of tutorials on how how to use mutt and offlineimap. I have had a mutt and offlineimap setup for quite a long time, however I decided to tune it a bit lately.
Why mutt? There are numerous articles out there referencing more efficient email handling. Merlin Mann’s InboxZero is quite popular. The basic idea is to never let any mail unprocessed, don’t show notifications and only check mails in certain intervals. If you use Apple Mail, you can use Mail Act-On which is quite nice as well. However mutt is much more efficient and flexible in it’s mail processing capabilities. At the same time it’s much faster than thunderbird.
I had switched to thunderbird when I discarded my old hackintosh netbook, with it’s slow Atom CPU. The most annoying part to me it seemed, was the fact that it would always bug me with nagscreens when my laptops connection dropped. (and the power consumption)
The offlineimap setup I use thus makes some use of NetworkManager to start and stop offlineimap and msmtpq when an internet connection exists. First of all I have two offlineimap setups, both offlineimap setups create the mailbox folders for mutt automatically as described in the offlineimap manual.
[general] accounts = Gmail maxsyncaccounts = 1 # This will suppress anything but errors ui = Noninteractive.Quiet [mbnames] enabled = yes filename = ~/.mutt/mailboxes header = "mailboxes " peritem = "+%(accountname)s/%(foldername)s" sep = " " footer = "\n" [Account Gmail] localrepository = GmailLocal remoterepository = GmailRemote autorefresh = 10 quick = 5 [Repository GmailLocal] type = Maildir localfolders = ~/Mail/GMAIL restoreatime = no [Repository GmailRemote] type = IMAP ssl = yes remotehost = imap.gmail.com remoteuser = firstname.lastname@example.org nametrans = lambda foldername: re.sub ('.*Drafts.*', 'drafts', re.sub ('.*Sent Mail.*', 'sent', re.sub ('.*Starred.*', 'flagged', folder))) folderfilter = lambda foldername: foldername in ['.*INBOX.*', 'archives', 'pending']
Since I use the same hotkey for drafts and sent mail, I use nametrans to
have these folders have a consistent name across all my mail accounts.
The password for email@example.com is set in the .netrc file. Also this
is the minimal sync setting for whenever I’m on 3G or similar. Since my
laptop has an internal wireless and ethernet device eth0 and wlan0 are
what I use to assume that there is proper internet existing.
NetworkManager will thus call my dispatch.d script which will in turn
offlineimap and msmtpq.

daemonize is a little tool for running any command as daemon. With pid- and lockfile support. Since I use msmtp-queue to send mails and I may or may not want to send mails when I’m offline msmtpq -r needs to be run whenever I connect to the internet. Msmtprun is just that, a script that tries to run msmtq -r once every 5 minutes.
#!/bin/sh while [ 1 ]; do /usr/bin/msmtpq -r & sleep 300 done trap "echo -n exiting... ;kill $!;exit" INT TERM
A mutt config that should work in both linux and osx(with minor adjustments) can be found on my github page
I also recently switch to using mu instead of mairix, it’s much faster and more stable than mairix,
You basically do
mu index --quiet --maildir ~/Mail
once and then add something like
31 */2 * * * /usr/bin/mu index --quiet --maildir ~/Mail
