Updated Postfix + VDA (maildir++ quota support) for Centos/RHEL 6 packages

I've uploaded them to packagecloud.io so anyone could use them: https://packagecloud.io/nstorm/postfix-vda-el6

Installing these packages are as easy, as running couple of commands to add a custom repo and install a package, thanks to packagecloud.io (https://packagecloud.io/nstorm/postfix-vda-el6/install):

CODE: SELECT ALL

curl -s https://packagecloud.io/install/repositories/nstorm/postfix-vda-el6/script.rpm.sh | sudo bash

Then you just install postfix and optionally perl scripts: 

CODE: SELECT ALL

yum install postfix postfix-perl-scripts

Source RPM are also available on packagecloud.io.

quick install

curl -s https://packagecloud.io/install/repositories/nstorm/postfix-vda-el6/script.deb.sh | sudo bash

Configure Postfix VDA

1. Edit the postfix configuration file /etc/postfix/main.cf and add the lines below

virtual_mailbox_limit_override = yes virtual_overquota_bounce = yes virtual_mailbox_limit_maps = hash:/etc/postfix/vquota

2. Create the file /etc/postfix/vquota containing the mapping from an email address to the maximum mailbox quota in bytes. If you wish to be exact, 1KB equals 1024 bytes while 1MB equals 1024KB or 1048576 bytes.

johndoe@acme.local 10485760 janedoe@acme.local 2097152

John Doe got a 10MB quota while Jane Doe got 2MB.

After creating this file, execute postmap /etc/postfix/vquota. This will generate/etc/postfix/vquota.db, the actual file that will be used for the lookup.

Available options and examples

• • These are only the options available in our VDA patch. Look into the Postfix documentation to see how to setup Postfix

  • to use virtual transport. If you use other transport than virtual, this patch is not for you.
