Is there a hack available somewhere to split huge (tens or hundreds of
MB) mbx-format mailboxes such as sendmail creates in /var/mail/? I've
done a Google search and looked at a few things at http://www.ugu.com/
but I haven't found anything useful.

It would need to be smart enough to handle large MIME-encoded
attachments.

Thanks,

perl -pe 'BEGIN {$out="aaaa";}
          if (/^From /) {
            open(STDOUT, "> $out") || die "cannot open $out: $!\n";
            ++$out;
          }' /var/mail/my_big_mailbox

No, NO, NOO! This certainly is not an appropriate way to separate mbox
messages.

formail, which is part of the procmail package, does this properly.
Recommended.

Would you care to elaborate on that?  When does this fail with mbox format?

Yes, that is definitely a better tool for the job.

I had exactly this problem, ran that script, and it did fine for me.
This doesn't mean there can't be problems, but to move a
pop3-leave-mail-on-server users mbox from /var/mail to the new
cyrus-imap system, it worked like a charm.

Your mailage may vary. ;-)

Some people use the word 'From' at the start of a line.

Yes, and mbox format requires that this be munged; historically
a > was inserted at the beginning of such lines, though I think
a space would have been a better choice.

Really?  Under Solaris 2.6:

% cat /var/mail/chuck
From chuck Wed Aug 23 12:55:28 2000

        by bjork.codefab.com (8.11.0/8.11.0) id e7NGtRH15063
        for chuck; Wed, 23 Aug 2000 12:55:27 -0400 (EDT)
Date: Wed, 23 Aug 2000 12:55:27 -0400 (EDT)



Subject: test
Content-Length: 18

A test.
From me.

whereas, under Irix 6.4:
-------------------------------


Subject: a test of From stuff

Mime-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
User-Agent: Mutt/1.2.4i

This is

Quote:>From me
and not
>From someone else

As said above, I was under the impression that the mbox-format
specifically specified that the occurence of the word "From " first on
a line would be munged to ">From " and that "everyone" knew this and
demunged that while reading mboxes. So exactly how do you produce such
an mbox-file in /var/mail ?

If the mbox content spans month boundaries, use mms.pl (Mailbox Monthly
Splitter) from http://www.netrus.net/users/troc/perl.html
