So how do you limit the mailbox size for users configured with the Postfix mail server?

It is good choice to avoid problem (disk DoS) by limiting mailbox size. This will avoid the user or hacker to eat up all hard disk space.
Display the default mailbox size limit
Type the following command:
# postconf mailbox_size_limit
Output:
mailbox_size_limit = 51200000
51200000 bytes is default mailbox size limit.
Display the default maximum size in bytes of a message
Type the following command:
# postconf message_size_limit
Output:
message_size_limit = 10240000
Setup new mailbozsize limit
Open file /etc/postfix/main.cf and
# vi /etc/postfix/main.cf
Add/modify/set values as follows:
mailbox_size_limit = 30000000
message_size_limit = 10240000
Save and restart postfix mail server:
# /etc/init.d/postfix restart

how to make diffrent mail box sizes for diffreent users or groups
Hi, you have to use LDAP or Mysql so you may create an attribute that defines the mailQuotaSize for each user.
In my site, I have a complete guide to do this, but is in spanish.
Regards,
Why don’t you post the link? Some of us may actually speak Spanish.
My maths is a little rusty but I think that 3 is a smaller number than 5. In other words in effect you have shrunk the mailbox_size_limit. Perhaps adding a zero to 51200000 or just doubling the figure would do it.

Scrap that. I have just realised that the post is to shrink the mailbox size. Its just that yesterday I was looking to grow the mailbox size and got fixated upon that idea.
