Add the following (pseudo) commands to your script.

zcat (the gziped .mbox files) > some/temp/file
bin/arch --wipe listname some/temp/file
rm some/temp/file

This will rebuild the archives using only the posts from the saved,
gziped .mbox files.

There are issues remaining. As I mentioned in another post just today,
this renumbers the archive messages and changes their URLs. This may
or may not be important to you. See
and the FAQ it refers to.

There may be issues with scrubbed attachments hanging around. You can
address this by adding

rm -r archives/private/listname/attachments/*

to the script before the bin/arch rebuild, but this will most likely
invalidate any links to scrubbed attachments in old digests (and
messages if you scrub messages) that people may have saved.

The links in the rebuilt archives will be OK.
