+Mail delivery agent (or MDA for short) is a piece of software that performs the
+final step of mail transfer: saving it into user's mailbox.
+This is invoked either by SMTP server (MTA), mail fetcher, or chained from
+other delivery agent to perform such tasks as mail filtering, saving to
+different folders, or forwarding to different addresses.

+Following software can deliver to Maildir mailboxes:

 Internet Mail Access Protocol servers that can interoperate with notmuch.
 It is of note that IMAP protocol supports storing so-called [keywords](https://tools.ietf.org/html/rfc3501#page-11) (user-defined flags) which are mostly equivalent to notmuch tags.
-Unfortunately Maildir does not have standard way to encode keywords, so there are extensions neccessary to store that information.

 Up to 26 different keywords can be stored per-maildir using Maildir flags a-z.
-Their meaning is defined via `dovecot-keywords` file which is simple, well-defined text file which maps each letter to specifig tag/keyword.
+Their meaning is defined via `dovecot-keywords` file which is simple, well-defined text file which maps each letter to specific tag/keyword.
 If more than 26 keywords appear in one Maildir then some of them are stored in [dovecot-specific](http://wiki.dovecot.org/Design/Indexes/MainIndex) [index files](http://wiki.dovecot.org/IndexFiles).
 Dovecot's dsync will sync keywords into this format.

+The origin of Maildir++ format which was also adopted by dovecot, among others.
+Ships many useful commandline tools.
 
 It stores keywords in [courierimapkeywords](http://www.courier-mta.org/imap/README.imapkeywords.html) inside the maildir.
 It supports arbitrary amount of keywords, but unfortunately actually reading them is rather convoluted process.
