+Check new mails over IMAP protocol.
+
+Dependencies:
+
+- Python3
+
+New mails are notified through a notification like this:
+
+ +---------------------------------------------------+
+ | +---+ |
+ | |\ /| donald@disney.org has 3 new messages |
+ | +---+ |
+ | Latest From: Mickey Mouse <boss@disney.org> |
+ | Subject: Re: pay raise |
+ | |
+ | Not after what you did yesterday. |
+ | Daisy told me everything [...] |
+ | |
+ +---------------------------------------------------+
+
+Text will be cut if the mail is too long.
+
+ myimapcheck = lain.widgets.imap(args)
+
+The function takes a table as argument. Required table parameters are:
+
+Variable | Type
+--- | ---
+`server` | string
+`mail` | string
+`password` | string
+
+while the optional are:
+
+Variable | Meaning | Type | Default
+--- | --- | --- | ---
+`port` | IMAP port | int | 993
+`refresh_timeout` | Refresh timeout seconds | int | 60
+`header` | Text to show before value | string | " Mail "
+`header_color` | Header color | string | `beautiful.fg_normal` or "#FFFFFF"
+`color_newmail` | New mail value color | string | `beautiful.fg_focus` or "#FFFFFF"
+`color_nomail` | No mail value color | string | `beautiful.fg_normal` or "#FFFFFF"
+`mail_encoding` | Mail character encoding | string | autodetected
+`maxlen` | Maximum chars to display in notification | int | 200
+`app` | Mail program to spawn on click | string | "mutt"
+`shadow` | Hide widget when there are no mails | boolean | false
+`is_plain` | Define whether `password` is a plain password (true) or a function that retrieves it (false) | boolean | false
+
+Let's focus better on `is_plain`.
+
+You can just set your password like this:
+
+ args.is_plain = false
+ args.password = "mypassword"
+
+and you'll have the same security provided by `~/.netrc`
+
+**Or** you can use a keyring, like [python keyring](https://pypi.python.org/pypi/keyring):
+
+ args.password = "keyring get password"
+
+When `is_plain == false`, it *executes* `password` before using it, so you can also use whatever password fetching solution you want.
+
+You can also define your custom icon for the naughty notification. Just set `lain_mail_notify` into `theme.lua`.
