Courier-IMAP is a server that provides IMAP access to Maildirs. This IMAP
|
||
|
|
server does NOT handle traditional mailbox files (/var/spool/mail, and
|
||
|
|
derivatives), it was written for the specific purpose of providing IMAP
|
||
|
|
access to Maildirs.
|
||
|
|
|
||
|
|
"Maildir" is a directory-based mail storage format originally introduced
|
||
|
|
in the Qmail mail server, and adopted as an alternative mail storage
|
||
|
|
format by both Exim and Postfix. Courier-IMAP is popular on
|
||
|
|
Qmail/Exim/Postfix sites that are configured to use maildirs. The primary
|
||
|
|
advantage of maildirs is that multiple applications can access the same
|
||
|
|
Maildir simultaneously without requiring any kind of locking whatsoever.
|
||
|
|
It is a faster and more efficient way to store mail. It works particularly
|
||
|
|
well over NFS, which has a long history of locking-related woes.
