Hi,
I am using Postfix with the virtual agent to deliver to Maildirs for
LDAP users. We use
Courier IMAP to pick up mail. This all works fine, but I would like to
provide Sieve for
users. I have been looking at maidag
(http://www.gnu.org/software/mailutils/manual/html_node/maidag.html).
Would it be reasonable to use 'pipe' and pass mail for delivery to
maidag instead of 'virtual'?
I'm interested to note that I can find no references to maidag being
used with Postfix. Can
anybody foresee problems with this?
In particular I am wondering if there are any subtle differences between
the Maildir format
used by Postfix's virtual (which I suspect uses standard Maildir since
it doesn't appear to
have a use for folders), Courier (which seems to use 'Maildir++') and
maidaig (which
presumably must have some form of extension if it is delivering mail
into folders). Could this
preclude all 3 programs using the same Maildirs?
I am also wondering if there is an unreasonable overhead involved. pipe
will have to spawn
maidag for each Maildir; is this reasonable? I am unable to determine if
virtual has to do the
same thing. Grepping my logs I see virtual seems to deliver multiple
mails using a single PID,
however virtual(8) shows that it can use a range of UIDs, which I assume
requires multiple
processes(since virtual is not running as root)?
Thanks for any help,
Ian
