Users can create infinite mailboxes

Hi @andris9 just sharing that we looked at on the handler for onCreate and don't see that it prohibits users from creating an infinite amount of mailboxes nor does it check the user's current quota.

@andris9 the max number of folders (I think) in Gmail is 10,000 (they use labels) per below:

https://developers.google.com/gmail/api/reference/rest/v1/users.labels#:~:text=Labels%20are%20used%20to%20categorize,a%20user's%20mailbox%20is%2010%2C000

Yeah, all these limits are implementation-specific. The test server instance uses Arrays, and you have to consider issues like running out of memory if the array grows too large, but WildDuck itself stores mailboxes as database entries, and these are not hard-capped like Maildir folders, where you need to count inode values. There probably should be some sanity check limit, though. Maybe as well 10k like Gmail, or 100k, I'll add this to our JIRA backlog (WildDuck development happens mostly off-Github).
