Do you really want new email to be deliverable while the account is in 
this state? I'd rather return to sender than accept and silently delete 
after a few weeks.

If you can live with bouncing new mail, then you can give the user a 
read-only mailbox with something like:

1) In cyradm, setaclmailbox user.joeschmo joeschmo lrsp
2) mv `mbpath user.joeschmo`/*. /var/imap/held-users/joeschmo
3) Send them a new message, making sure to use a UID higher than 
anything already there (otherwise the message might be hidden from 
clients in disconnected mode). Probably just email it.
4) reconstruct user.joeschmo
5) Put something into aliases or accessdb or virtusertable or LDAP that 
has the effect of bouncing incoming mail with an appropriate message

To undo,

1) rm `mbpath user.joeschmo`/*. (your message should be the only one)
2) mv /var/imap/held-users/joeschmo `mbpath user.joeschmo`
3) reconstruct user.joeschmo
4) setaclmailbox user.joeschmo joeschmo lrswipkxtecda (or whatever it 
was originally, if you're on a pre-2.3 version)
5) Remove the alias/accessdb/virtusertable bounce
