Complete mailbox delete?

[Charles Bradshaw]

Hello info-cyrus,

I'm sure this question has been asked before, but I can find no
definitive answer. 

I have used cyradm to delete some virtual domain mail boxes.

cyradm lm now lists them as "DELETED" and
my  /var/spool/imap/domain/s/somedomain.com/u/DELETED/user/ now contains
copies of the deleted mail boxes.

Assuming that the old user has no use for the contents, is it safe to
just delete these?

Supposing that all of the somedomain.com users are now gone can I just
remove .../somedomain.com and all its sub directories?

TIA
