Hi, Just to let everyone know of a neat "feature" I figured out today during my conversion from an old Postfix mail server to a set of two clustered qmailldap ones. I'm gradually moving users over to the new server and have already created ldap entries for them, mainly so that I can use ldap as an address book. As I move users over I put a .forward on the old mail server (accepting mail for @domain1.com) to [EMAIL PROTECTED] Postfix then forwards the mail to that DNS A record which is one of the two qmailldap boxes. Works great. The first problem I ran to was in using the two as an smtp server for domain1.com. If one of the new users sent email through the clustered servers for [EMAIL PROTECTED] it will fail as all the accounts I haven't moved over yet have accountStatus set to disabled. So I got around that by installing a 3rd qmail-smtpd server and have everyone send mail through that. It knows via smtproutes to send mail to @domain1.com to the old server and @mail.domain1.com to the new one. Pretty easy stuff. Well today I ran into a problem where an old user sent a new user a mail that was then re-directed by bogofilter to [EMAIL PROTECTED] I hadn't setup the -catchall mailalternateaddress yet so the email bounced. Except the bounce was to a qmailldap account. Qmail gave up and delivered it to the postmaster, like it should. So I looked into mailfowardaddress, which worked fine except it seemed a little goofy for me. Qmail would accept the mail and the forward it to the old server, probably ruining any Addressed-To fields (I'm not 100% sure of that). Anyway it struck me: extend clustering to the postfix server! 5 minutes later I have a working QMQPD instance on the old postfix server (thanks to http://www.din.or.jp/~ushijima/qmail-conf.html). It listens on port 628 so it doesn't interfere with Postfix. Luckily the person that installed Postfix used Maildir delivery so all I had to to was startup qmail-send and have it deliver into the user's Maildir. I then changed the mailHost to the old Postfix server for the old accounts and mail went from the qmail cluster over to the postfix server flawlessly. I'll eventually writeup a howto on how I did this migration to help out the community. If you have any particular things you'll like to see addresses, let me know.
