Hell yeah it helps. Hm, they're compiled in by default in Ubuntu, wonder
if that means Debian too. Also...

There is a plug-in for sieve.

Then you can back up mail directories with thinks like rdiff and not
pull in the whole mbox file into the backup again. Just the new
mail. (GRIN)

While I do think Maildir is a lot better than mbox, applications like
rsync, rdiff-backup, etc, copy only what's changed in files, so
rsync'ing a mbox is actually efficient.

Uh, no, thanks. I far prefer mbox's problems to maildir's.

Huh? You do realize that diff does work on individiual lines in a file
so effectively no difference.

Maybe it's because I keep d-u messages is semi-annual history
folders so directories never get above 10,000 files, but what
problems do Maildirs have?

Needing to open many files instead of one?

I'll take that over an errant EOF wiping out a large chunk of a
directory.

Yes I can restore from backup, but
(a) the bug that caused the errant EOF is still there, and
(b) bringing back the back-up emails without introducing duplicates
or overwriting new mails is a hassle.

Needing to deal with that many files in any capacity, ever. I've
had the displeasure of being the administrator of a qmail setup that
would accept all mail (smtp-time rejection, what's that!?) then filter
then generate bounces to bogus email addresses in spam. Yeah, 50,000
maildir queues that take 20 minutes to stat are no fun. That pretty
much swore me off that idiotic idea.

Let's see. I've been using mbox since the early 90s with my first
Netcom account and elm. Or was it late 80s? Anyway, let's just say
about 15 years. In that time know how many EOF problems I've hit in all
of my mail in 15 years?

0.

I've had 2 hard drives take a nosedive on me in that time.

Or not to put too fine a point on it, opening up one maildir
directory with more than, say, 2000 messages in it will have wasted more
time than I have ever had wasted by "errant EOFs".

Or in my case, not. I guess you could say that the bug that caused
my hard-drive to eat itself is still there...

Not so much any more. Pull out archives, merge, run "remove
duplicates" tool, done. But then, I haven't had to do that, either,
since when I lose my mail stores to hard drive failures I generally am
no concerned about the "merge" portion.

That's qmail's fault, not that of Maildir.

For the record it is compiled in on the Debian version of dovecot.

Unfortunately this is bare bones, the scripts need to be handwritten. I
was hoping for an inteface similar to TBird's internal filtering. IE,
something parent friendly.

My "~/Maildir/.ML_devel.linux-kernel@vger_kernel_org/cur" has currently
153.000 messages with arround 3 GByte and even mutt open it localy in
less then 4 minutes without "hcache"

I am using ext3 and used "tune2fs" to add the "dir_index" which
increased the speed by faktor 6. I should note, that I am already using
a Raid-1 with two 74 GByte SCA drives plus Hotfix of 15.000 RpM.
