The limits in maildirsize file are ignored by Dovecot as long as you
defined quota_rules. So don't bother looking at them.

Then it means that Dovecot didn't see the userdb_quota_rule for some
reason. Do you mean here that deliver didn't regenerate it correctly?

It's again beginning to sound like deliver isn't doing a userdb lookup
and getting the userdb_quota_rule.

So wrong user's userdb_quota_rule was used? That doesn't really make any
sense..
