NOTICE


I am currently looking for a new maintainer for this patch. If someone like to take maintainership for this. Contact me (kiwi at oav dot net).

Description


I work for a ISP and I love postfix a lot.
The original Postfix Virtual Delivery Agent lacks from some features that are usefull for ISP's:

Incompatibilities


Starting with snapshot 20011210, a new map has been added to postfix. Since this release virtual_static_uidgid,virtual_static_uid and virtual_static_gid are now removed from this patch. Please use the map static instead.
Example :
# Before snap 20011210
virtual_static_uidgid = yes
virtual_static_uid = 200
virtual_static_gid = 200
virtual_uid_maps = 
virtual_gid_maps =
Now you can use : 
# Starting with snap 20011210
virtual_uid_maps = static:200
virtual_gid_maps = static:200
Which is much better for smaller configuration file and easier to understand.

New features


Now virtual handles uid/gid per domain. Thank to Matt <grpmind+postfix at boromir dot vpop dotnet> for this. Example : 
# Postfix main.cf configuration file
virtual_uid_maps = hash:/etc/postfix/uids
virtual_gid_maps = hash:/etc/postfix/gids
In maps : 
# /etc/postfix/uids
user@domain.com	10001
user@domain.net	10002
@dot.com	20001
@dot.net	20002

# /etc/postfix/gids
user@domain.com	2000
user@domain.net	2000
@dot.com	5001
@dot.net	5002
Have fun... :)
Added 12/08/2002: support for per domain softquotas, like this example : 
virtual_mailbox_limit_maps = hash:/etc/postfix/vquota
In the /etc/postfix/vquota: 
user@dot.com	2000000
user@dot.net	2000000
@dot.com	5192000
@dot.net	8192000
Warning: This will enabled only with postfix snapshots 200207019 or newer.

Sample configuration


Note that this configuration is just a dummy example I use for testing purposes, it can be used for understand better how this patch works
main.cf configuration
Here is in short the configuration for main.cf file : 
# I use only virtual as localdelivery... This permit me to have full
# virtual domain hosting without using a lots of maps
mailbox_transport = virtual

# All my virtuals users are located on a separate disk 
virtual_mailbox_base = /var/mailusers

# Maps of virtuals users
virtual_mailbox_maps = hash:/etc/postfix/vmailbox

# All ids < 1000 are bad ids...
virtual_minimum_uid = 1000

# I use same uid and gid for all my users
virtual_uid_maps = static:4000
virtual_gid_maps = static:4000

# A maximum limit of a mailbox
virtual_mailbox_limit = 100000000

# Limits only INBOX part (usefull when
# using when you have IMAP users)
virtual_mailbox_limit_inbox = yes

# maps of soft disk quotas
virtual_mailbox_limit_maps = hash:/etc/postfix/vquota
virtual_mailbox_limit_override = yes

# I use Courier IMAP compatibles files.
virtual_maildir_extended = yes

# Usefull for Courier IMAP..
virtual_maildir_suffix = Maildir/

# Generate maildirsize files or not
virtual_create_maildirsize = yes

vmailbox maps file
The software diskquota can be user either on Maildir format or mailbox 
# This are maibox users
user1@domain.com	com/d/do/domain.com/user1
user2@domain.com	com/d/do/domain.com/user2
# This are Maidir users
user1@domain.net	net/d/do/domain.net/user1/
user2@domain.net	net/d/do/domain.net/user2/

vquota maps file
This file contains in bytes the maximum diskspace authorised per emails. 
# domain.com are unlucky one... they have a max to 2M diskquota
user1@domain.com	2048000 
user2@domain.com	2048000 
# domain.net are more lucky... and some don't have any limits (0 !)
user1@domain.net	5192000
user2@domain.net	0

And now ?
For this example I used flat files and hash: postfix dictionary, now you can use allmost every postfix dicts, like ldap, mysql, hash, static, tcp and so on.

Contact / Author


I'm not the author of Virtual Delivery Agent for Postfix. But this patch was make by me for my work needs. I was taken from a patch from Adrian Zurek (please have a look at the postfix-user mailing list for more information) that supported only mailbox format. I added support for maildir storage and few new options.
