I would like to be able to use, for example, a subroutine which

characters to the right, and leaves the domain name untouched.
Who is the adversary? Would DES be a better choice?
Note, I have added a resource called ADDRESSMODIFYCODE which will allow
you to modify the displayed email addresses in message headers. Note,
it does not affect the URL portion, that is controlled by MAILTOURL.
With the new resource variable additions, one can split the local-part
and domain part so address harvesters will not get the addresses in
URLs.
I'll try to send a follow-up message this evening on what the effects
of SPAMMODE will have in the next release.
Hm, if you profiled it, I'd like to see the results.
I didn't use a profiler - I just plotted times from a log file. There
was a dot for each run of MHonArc and they all lined up in a straight
line.
I just did a profile of my MH inbox (237 messages) at work:

This is MHonArc v2.3.3, Perl 5.005_02 on a SUNW,Ultra-5_10 running
Solaris 2.6 with 256M of RAM.
Since some of the mail has binary attachments, base64::b64decode
shows up as number 2. For normal mailing lists, base64::b64decode
may never be called since binary attachments are not too common.
I'll try to do some runs on machine at home this evening. It is a PII
350 running Linux and will out perform the Sun even though it only has
128M of RAM (btw, RAM is not an issue unless swapping occurs). I'll
try do some tests doing subject and author sorting since I have made
modifications to the sorting code which should significantly improve
subject and author sorting. I'll compare the times to MHonArc v2.3.3.
Note, performance will vary depending on your data. If there are alot
of binary attachments, you'll take a hit. Also, if there is alot of
non-latin-1 data, there can be a significant performance hit. If your
data is normally non-latin-1, you may want to look into the
DECODEHEADS, CHARSETCONVERTERS, and the "asis" option to the
m2h_text_plain::filter.
