Hi, I used this tutor Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 12.04 LTS) and have some issues with quota. unused parameter: virtual_overquota_bounce=yes unused parameter: virtual_maildir_limit_message="The user you are trying to reach is over quota." unused parameter: virtual_maildir_extended=yes unused parameter: virtual_mailbox_limit_override=yes I know that I can comment this line but I get infos about mailboxes quota that is about 60% but in virtual uiseres table in mysql I set 0. So I think that problem will be vith VDA patch so I patch my postfix again and install but still I get the same error. mail_version = 2.9.6 but I use apt-get update & upgrade is there any error? How can I fix it? How can I tell postfix to not use quota or read unlimited (0) as really unlimited?
