Thanks for that.  I keep the archives in files of 1K emails, so it would be easy
to do that.  The position was that for a long time all of my work and
personal email passed through my main computer here at home, and so volumes were
high. The work arrangement has changed now, so that there is (relatively),
little traffic. Not to mention that so many linux project mailing lists are so
much quieter than once they were.  My current wordlist works very well for my
current needs, but I will bear the advice in mind.
