There is a different problem here: you shouldn't alter a message that
is stored in IMAP. You should create a new message (with markup
removed) in the same folder, and then delete the old one.

This does mean that the MUA will have to download the message again.
Which should happen anyway after you alter the message server-side,
since otherwise the MUA shows the locally cached message (without
altered headers) to the user.

For details on what you can and cannot do, please seek for advice on
the dovecot mailing list.

IMHO, removing the markup is simply not a good idea: probably easier
to use headers only (i.e. no subject tagging), and then use IMAP flags
to highlight spam messages for the user. These can be unset later
without 'nasty' tricks.
