when running /scripts/upcp

I can see messages like:

MailBox (michaela@xxx.com) [critical]
MailBox (chandram@xxx.com) [warn]
MailBox (wayne@xxx.com) [critical]


now I'm wondering how to get those warnings without running /scripts/upcp (I did look in upcp script listing but couldn't find it.
), because otherwise I don't see way how to know state of mailbox quotas without logging in Cpanel of each site.

Any ideas ?
