Are you thinking of hooks for strong encryption in place of
rot13? Perhaps running the list through an anonymizing remailer
would be just as effective.
No...that would cause export problems. I would like to be able
to use, for example, a subroutine which performs rot11 on the
local part, rotates the entire local part two characters to the
right, and leaves the domain name untouched.
That would probably mean having a way to customize mha-dbrecover
to use the subroutine's "un-munge" counterpart.
By the way, I benchmarked MHonArc the other day as it rebuilt a 60,000
message archive from raw email, 870 messages at a time. It took about
a day on a K6-2 300 with 256 MB of ram.
Interestingly, each chunk of 870 messages took about the same amount
of time to run, so in this mode of operation I'd say time requirements
are O(n) where n is the number of messages.
Hm, if you profiled it, I'd like to see the results.
