Setup new mailbox size limit

Login as root and type the following command to edit main.cf

vi /etc/postfix/main.cf

Default, the limit for any local mailbox or maildir is 50 MB but, this can easily be changed with by using this directive in the main.cf file.

mailbox_size_limit=102400000

This changes the mailbox limit to 100 MB. Or you can make it umlimited by using a “0”.

mailbox_size_limit=0

Setup new message size limit

Default message size is 1 MB, example changes the message size limit to 2MB. Open file /etc/postfix/main.cf and add/modify/set values as follows

message_size_limit = 2048000
