That's a real problem. Subscriptions are a basic IMAP feature and it 
should never be slow to get a response to a LSUB command.   
Unfortunately, MM doesn't log that pane's activity.

I believe that is a red herring. That array seems to just be a way of 
maintaining exclusions from the server-side subscription list.

Every time I take an account offline and back online, MM connects as 
many sessions as it is set to for that source (3 by default) and on one 
of them it issues a NAMESPACE command followed by a LSUB command for 
each namespace. That provides what it needs to build its active source 
list, which is stored NOT in Sources.plist, but in Mailboxes.plist. I 
see no wildcard LIST commands used for sources using Dovecot, GMail, or 
CGP IMAP servers.

I don't see much risk, since all you would want to manually add for a 
new source mailbox is a dictionary at the right level with the 
'previousUUID' and 'uuid' keys in MM's pseudo-URL format, being sure to 
fix the 'previousUUID' key of the relevant  existing one if you want to 
insert above the end of the list. The only potential errors I see are 
typos or getting the 'previousUUID' linkage wrong.
