Jan is (mostly) correct ... we absolutely can't rely on Ingo having  
any knowledge of the current state of the mailboxes on the server,  
since there are a multitude of ways to change the mailboxes outside of  
IMP.

That being said... it should be possible to *notify* the user in the  
following situation:

1) A mailbox is altered in IMP
2) That mailbox is a member of one or more rules in the current  
filtering backend.

In this case, there is nothing wrong with reminding the user to update  
their filters, as long as nothing is changed automatically.  Even  
better would be to link to an Ingo page that filters rules by a  
mailbox name, so you can instantly see which rules are connected to an  
individual mailbox.

Reopening ticket for these two features.

No.  There is no IMAP equivalent to mailbox names as there is to  
CONDSTORE/QRESYNC IMAP extensions (i.e. mod sequence values for  
messages).
