I did some work for a different purpose which should work for you:
I use Exim as my MTA and deliver using LMTP. You need to add to your MTA
configuration for this solution.
Touch a file (name is the account name) in a "suspend" directory and have the
MTA queue messages if the file exists. This prevents delivery while things are
changing.
Rename the account from user.account to user.account-pending, keeping the same
partition so that the rename is quick. Create a new account for user.account
and put your single message in there. Do a reconstruct to make the message
visible.
Touch a file in a "pending" directory. Make your MTA check for the file before
delivery and if it is present, make it deliver to "account-pending" instead.
Remove the file from the "suspend" directory to allow deliveries to resume.
If you decide to resurect the account just remove user.account and rename
user.account.pending back to normal.
(I have included my Exim routers below. Note the ability to deliver to the new
account using a header.)
Hope this helps.
Phil.
