Just having another look at http://wiki2.dovecot.org/MailServerOverview
, it seems to have some statements in it which are misleading, and some
which are really ... well ... wrong.
Quote: "With the possible, optional, exception of the deliver MDA,
Dovecot is not involved with reception, delivery, and storage of mail.
That function is provided by a MTA such as postfix
<http://www.postfix.org>. It is the MTA that determines where and how
mail is stored - Dovecot must then be configured to retrieve the mail
accordingly." (Entered by user "amfes".)
This contains a significant proportion of poppycock.
Dovecot includes extensive functionality for the storage (as in the
action of storing) of e-mail as well as retrieval, in the shape of the LDA.
Using Dovecot's LDA is /required/ in the case of Dovecot-specific mail
storage formats (sdbox, mdbox).
With mbox, use of the Dovecot LDA is advisable since it will guarantee a
locking strategy which is compatible with Dovecot's mail retrieval
And in any case, use of the Dovecot LDA has merit in that it should
guarantee line-up between the mailstore configurations used for storage
It is NOT the MTA that determines where and how mail is stored. It is
the PERSON who configures the system who decides this, and codifies that
configuration into whatever systems carry out local delivery and retrieval.
It IS true that use of Dovecot's LDA is optional, but to say that it is
a "possible exception" is misleading. People /should/ use the Dovecot
LDA if they are using Dovecot IMAP/POP, and the /option/ is to use the
MTA's local delivery system /if/ it is so indicated on a particular system.
Quote: "Again, it bears repeating, Dovecot /is not responsible for mail
delivery or storage/. Any questions on these issues involve your MTA and
MDA. Get those working first." (Entered by user "DanielMiller".)
Again, contains quite a lot of misleading nonsense.
"Mail delivery" includes the hand-off of the message by the MTA to the
LDA, and the storage of the message by the LDA. The LDA should probably
be Dovecot, so really Dovecot /is/ partially responsible for mail delivery.
"Storage" involves that placing of message into the message store. This
should be done by Dovecot, so Dovecot is responsible for this.
