They run within the server. I don't think there's much point in
separating them into other processes. So yes, you'd need embedded
interpreter but I don't think that's much of a problem.

Nice :)

I heard about similiar problem before too.. I couldn't really figure out
what it was that caused the problem. I've never seen it myself and I've
been using mboxes all the time.

What that error message means is that message header size is different
when rewriting mbox than what it was at last synchronization. But since
the syncing is done just before the rewriting, that should never happen.
Except if there's a bug somewhere..

If it's possible I would like to see that mbox file. Actually it could
be enough if you just hide the actual content in it. Here's a pretty
perl script for that:

perl -e 'while (<>) { if (/^From ([^ ]*) *(.*)$/) { $hdr = 1; print "From foo\@bar.org $2\n"; } elsif ($hdr) { if (/^$/) { $hdr = 0; print "\n"; } elsif (/^Date:/i || /^Status:/i || /^X-Status:/i || /^X-Keywords:/i || /^X-UID:/i || /^X-IMAPbase:/i || /^Content-Length/i) { print $_; } else { s/^([^:]+:) (.*)/("$1 "."X"x length($2))/e; print $_; } } else { s/./B/g; print $_; } }' < inbox
