+Keep your email in sync with OfflineIMAP
+======
+Mirroring your email to a local folder is the first step in taming your
+message pileup. Learn how in the third article in our series on 20 ways
+to be more productive with open source in 2020.
+![email or newsletters via inbox and browser][1]
+
+Last year, I brought you 19 days of new (to you) productivity tools for 2019. This year, I'm taking a different approach: building an environment that will allow you to be more productive in the new year, using tools you may or may not already be using.
+
+### Sync your email locally with OfflineIMAP
+
+I have a love/hate relationship with email. I love the way it allows me to communicate with people all over the world. But, like many of you, I get a lot of mail, much of it from lists as well as spammers, advertisers, and the like. And it builds up.
+
+![The OfflineIMAP "blinkenlights" UI][2]
+
+Almost all the tools I've tried (outside of the big mail providers) that work really well with large amounts of mail have one thing in common: they all rely on a local copy of your mail stored in [Maildir][3] format. And the most useful tool for that is [OfflineIMAP][4]. OfflineIMAP is a Python script that mirrors IMAP mailboxes to a local Maildir folder tree. I use it to create a local copy of my mail and keep it in sync. Most Linux distributions include it, and it is available via Python's pip package manager.
+
+The sample minimal configuration file is a good template to start with; begin by copying it to **~/.offlineimaprc**. Mine looks something like this:
+
+
+```
+[general]
+accounts = LocalSync
+ui=Quiet
+autorefresh=30
+
+[Account LocalSync]
+localrepository = LocalMail
+remoterepository = MirrorIMAP
+
+[Repository MirrorIMAP]
+type = IMAP
+remotehost = my.mail.server
+remoteuser = myusername
+remotepass = mypassword
+auth_mechanisms = LOGIN
+createfolder = true
+ssl = yes
+sslcacertfile = OS-DEFAULT
+
+[Repository LocalMail]
+type = Maildir
+localfolders = ~/Maildir
+sep = .
+createfolder = true
+```
+
+What my configuration does is define two repositories: the remote IMAP server and the local Maildir folder. There is also the **Account** that tells OfflineIMAP what to sync when it runs. You can define multiple accounts linked to different repositories. This allows you to copy from one IMAP server to another as a backup, in addition to making a copy locally.
+
+The first run of OfflineIMAP will take a while if you have a lot of mail. But once it is done, future runs take a _lot_ less time. You can also run OfflineIMAP as a cron job (my preference) or as a daemon constantly syncing between repositories. The documentation covers all of this, as well as advanced configuration options for things like Gmail.
+
+Now that my mail is copied locally, there is a whole range of tools I can work with to speed up searching, filing, and managing mail. And I'll talk about that tomorrow.
