The only way to store this is in the file system (well, or some other external
mechanism like memcached or somesuch.)

A convenient place is to dump the data in the current directory,
because each message has its own (persistent) directory, typically on
a ramdisk.

All of the files created by MIMEDefang start with an upper-case letter,
so if you name your persistence file starting with a lower-case letter,
you won't clash with any MIMEDefang files.

See MAINTAINING STATE in the mimedefang-filter(5) man page.
