## <span id="mda">**Filters and mail delivery agents**</span>
+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:
+
* [procmail](http://www.procmail.org/)
* Courier (or standalone): [maildrop](http://www.courier-mta.org/maildrop/)
* Dovecot: [dovecot-lda](http://wiki.dovecot.org/LDA)
* Postfix: [local](http://www.postfix.org/local.8.html)
* Exim: [appendfile](http://exim.org/exim-html-current/doc/html/spec_html/ch-the_appendfile_transport.html#SECTmaildirdelivery)
* Qmail: [qmail-local](http://qmail.org/man/man8/qmail-local.html)
-* OpenSMTPD: supports tuning via [.forward](https://www.opensmtpd.org/forward.5.html) files

Many MDAs also support filtering via [Sieve](https://en.wikipedia.org/wiki/Sieve_%28mail_filtering_language%29) language.
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.

The fully standard-compliant IMAP server.
Has efficient syncing and multimaster replication capability.

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.

-Further maildir specification: http://www.courier-mta.org/maildir.html
+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.

-* UW-IMAP supports MH folders and there is a patch for Maildir support.
-* Cyrus has it's [own mailbox format](http://www.cyrusimap.org/docs/cyrus-imapd/2.5.7/internal/mailbox-format.php), but stores messages as single files which should be indexable.
