How can I use fetchmail multidrop mode with qmail?</a></h2> + +(This information is thanks to Robert de Bath +<robert@mayday.cix.co.uk>.)<p> + +If a mailhost is using the qmail package (see <a +href="http://pobox.com/~djb/qmail.html">http://pobox.com/~djb/qmail.html</a>) +then, providing the local hosts are also using qmail, it is possible +to setup one fetchmail link to be reliably collect the mail for an +entire domain.<p> + +One of the basic features of qmail is the `Delivered-To:' message +header. Whenever qmail deliver a message to a local mailbox it puts +the username and hostname of the envelope recipient on this line. The +major reason for this is to prevent mail loops. <p> + +To set up qmail to batch mail for a disconnected site the isp-mailhost +will have normally put that site in its `virtualhosts' control file so +it will add a prefix to all mail addresses for this site. This results +in mail sent to 'username@userhost.userdom.dom.com' having a +'Delivered-To:' line of the form:<p> + +<listing> + Delivered-To: mbox-userstr-username@userhost.userdom.dom.com +</listing> + +A single host maildrop will be slightly simpler: + +<listing> + Delivered-To: mbox-userstr-username@userhost.dom.com +</listing> + +The ISP can make the 'mbox-userstr-' prefix anything they choose +but a string matching the user host name is likely.<p> + +To use this line you must:<p> + +<ol> +<li>Ensure the option `envelope Delivered-To:' is in the fetchmail + config file. + +<li>Ensure you have a localdomains containing 'userdom.dom.com' or + `userhost.dom.com' respectively. +</ol> + +So far this reliably delivers messages to the correct machine of the +local network, to deliver to the correct user the 'mbox-userstr-' +prefix must be stripped off of the user name. This can be done by +setting up an alias within the qmail MTA on each local machine. +Simply create a dot-qmail file called '.qmail-mbox-userstr-default' +in the alias directory (normally /var/qmail/alias) with the contents:<p> + +<listing> + | ../bin/qmail-inject -a -f"$SENDER" "${LOCAL#mbox-userstr-}@$HOST}" +</listing> + +Note this <em>does</em> require a modern /bin/sh.<p> + +<hr> +<h2><a name="R1">R1.
