Once the IMAP Mailbox app retrieves an email from the server, does the app delete the email from the in-box? If so, is this configurable to any degree? i.e. all/none delete or delete only from certain email addresses...
By default it does, and it also supports disabling it.
See imap.conf in the app.

# deleteWhenDone
#
# If true will delete messages from mailbox after indexing.
# Should note that deteleWhenDone overrides any caching and assumes that each time
# the script gets called all messages in the inbox are new.
#
# I have noticed if you do not delete mail. Checking for mail can get extremely slow.

deleteWhenDone = True <- default setting
