Space usage

If the max I can have on the account (regardless of users) is 3500 MB and I’ve currently reached a limit of 600 MB for the user I’m logged in as (the master account), how much more could I get without raising costs past what I already pay (through sponsorship)?

(Specifically, if I raise the size of an E-mail account by 100 MB.)

if you have 3500mb of space, you can give each of your emails accounts 3500mb limit. it doesn’t take away anything from your storage space like if you said you gave 600mb to john and 500 to mary, your space is still 3500, not 2400.

just the actual accumulation of storage space used with everythings adds up to your usage, ie, all of your email accounts actual used storage, your files on your server, your mysql files, etc.
