After the LOGIN do STATUS "User/somemailbox":

a0007 STATUS "INBOX/Rechnung" (UIDNEXT UIDVALIDITY UNSEEN RECENT) a0008 STATUS "User/lists@example.com/Announce" (UIDNEXT UIDVALIDITY UNSEEN RECENT) a0009 STATUS "User/system@example.com/INBOX-root" (UIDNEXT UIDVALIDITY UNSEEN RECENT) a0010 STATUS "User/test@example.com/Shared" (UIDNEXT UIDVALIDITY UNSEEN RECENT) a0011 STATUS "User/system@example.com/INBOX-mueller" (UIDNEXT UIDVALIDITY UNSEEN RECENT)

The first listing of "User/%" also lists the first folder of each user, which has been polled by STATUS before. This seems to occur one time (after the login) only.
