This is an external software intended to make handling virtual domains easier.

Supports Qmail and Postfix. See http://inter7.com/vpopmail.html

Dovecot supports authenticating against external VPopMail
5
[http://inter7.com/vpopmail.html] virtual domain manager. Dovecot must have
6
been configured with '--with-vpopmail' to enable this. You can check this with
7
'dovecot --build-options'. See also <VMailMgr> [HowTo.VMailMgr.txt] for another
8
similar virtual domain manager.

If the vpopmail database contains plaintext passwords, it can be used for
8
11
non-plaintext authentication as well.

15
* cache_key: If set, you can use 'auth_cache' with VPopMail. See <PAM>
13
16
[PasswordDatabase.PAM.txt] for more information about it.

17
* webmail=IP: If IP address is specified, connections from it are assumed to
15
come from webmail and VPopMail's webmail usage restrictions apply.
18
come from webmail and VPopMail's webmail usage restrictions apply. (v1.2+)
22
* cache_key: Like in passdb.
23
* quota_template=TEMPLATE: Template to specify quota rule, %q in value expands
24
to Maildir++ quota. (v1.1+)

args = webmail=127.0.0.1

args = quota_template=quota_rule=*:backend=%q

Using vpopmail quota's instead of dovecot
41
=========================================
43
You can use vpopmail quota's, rather than dovecot's by doing using the maildir
44
quota plugin, and configuring as below:
46
---%<-------------------------------------------------------------------------
49
quota_rule = ?:storage=0
51
---%<-------------------------------------------------------------------------
53
This works as follows: ? means, use an existing "maildirsize" file if present
54
(ie from Dovecot's quota), otherwise storage is unlimited.Vpopmail will
55
recreate the file if it doesn't exist when delivering new mail with its quota
