Change email quota and using domain template

[vermillion82]

Hi to all,

I just started using Plesk last and there's still lot more to learn.
I have a problem changing the email quota. I've tried changing the setting in the "Domain Template" but nothing happens after I clicked the ok/save button. Am I doing the right thing or is theres another way of changing the email quota in plesk ctrl panel. One more thing is, how to actually use the "Domain template"?

Hope somebody can help me...Thanks.
