Email quota

[catalyst]

I installed the Fedora 6 according to "Installing A LAMP System With Fedora Core 6" and installed ispconfig 2.2.11
When I created a user email account in ispconfig and found that there was no mail quota for me to input, there only had web quota in it.

How to solve this problem?

There is no problem at all. The mailquota and webquota for a user are identical and therefor there is only one input field.

If I specify the Space MB at ISPManager->Sites->myweb.com->Basic, then should I need to specify the WebSpace at "User & Email" ??
But I have seem two fields (WebSpace, EmailSpace) at "User & Email" from the online menu, why there are two fields and I only get 1 field?
Thanks

yes.

This second field is only for mbox based systems as the systemquota does not work reliably on mbox systems.
