-----Original Message----- From: cour@lists.sourceforge.net [mailto:cour@lists.sourceforge.net]On Behalf Of Will Yardley Sent: Friday, September 17, 2004 12:55 PM To: cour@lists.sourceforge.net Subject: [courier-users] multiple MySQL servers

Is there any mechanism to have Courier (IMAP / POP3) check more than one MySQL server (so that if one fails, Courier can still authenticate users)? I know that Postfix allows this if you're using MySQL for virtual maps / aliases.

The current documenation for authmysql doesn't seem to suggest that this is a possibility.

This doesn't have to be courier's problem...

I can see this would make it easier, but there are other ways to skin the cat. You cluster the database, and use ip failover scripts to move the live IP to the backup server in case of failure...

then everything in your world just connects to the live mysql server ip - no matter what box it's on.
