<Para>
|

<Command/archivemail/ is a tool written in &python; for archiving and
|
|
compressing old email in mailboxes.
|
|
</Para>
|
|
|
|
<Para>
|
|
By default it will read the mailbox <Replaceable/MAILBOX/, moving messages
|
|
that are older that the specified number of days (180 by default) to a
|
|
<application/mbox/-format mailbox in the same directory that is compressed
|
|
with &gzip;.
|
|
</Para>
|
|
|
|
<Para>
|
|
<Command/archivemail/ supports reading <application/Maildir/,
|
|
<application/MH/ and <application/mbox/-format mailboxes, but it will
|
|
always write archive files to <application/mbox/-format mailboxes that
|
|
are compressed with &gzip;.
|
|
</Para>
|
|
|
|
<Para>
|
|
<Command/archivemail/ has some support for being run as the root user on
|
|
user mailboxes. When running as root, it will &seteuid; to the owner of the
|
|
mailbox it is reading, creating any archive files as that user.

<Para>

When reading an <application/mbox/-format mailbox, <command/archivemail/ will
|

create a lockfile with the extension <filename>.lock</filename> so that
|
|
procmail will not deliver to the mailbox while it is being processed. It will
|
|
also create an advisory lock on the mailbox using &flock;.

<command/archivemail/ will also complain and abort if a 3rd-party modifies the
|

mailbox while it is being read.

</Para>

<Para>
|

<Command/archivemail/ will always attempt to preserve the mode,

last-access and last-modify times of the input mailbox. However, archive
|

mailboxes are always created with a mode of <application/0600/.

If <Command/archivemail/ finds a pre-existing archive mailbox it

<application/Delivery-date/,
|
|
<application/Date/ and
|
|
<application/Resent-Date/.
|
|
If it cannot find any valid date in these headers, it
|
|
will use the last-modified file timestamp on <application/MH/ and

<application/Maildir/ format mailboxes, or the date on the

<application/From/ line on <application/mbox/-format mailboxes.

<Title>Bugs</Title>
|

<SimPara>
|
|
There is no support yet for reading <application/MMDF/ or
|
|
<application/Babyl/-format mailboxes. In fact, <Command/archivemail/ will
|
|
probably think it is reading an <application/mbox/-format mailbox and cause
|
|
all sorts of problems.
|
|
</SimPara>
|
|
|
|
<SimPara>
|
|
<Command/archivemail/ is still too slow, but if you are running from &crontab;
|
|
you won't care. Archiving <application/maildir/-format mailboxes should be
|
|
a lot quicker than <application/mbox/-format mailboxes since it is less
|
|
painful for the original mailbox to be reconstructed after selective message
|
|
removal.
