I wrote a patch (or quick hack) to do this and have been running this setup in production for more than months without any problem. The patch for 5.4.3 is located at http://www.sigrity.com/oss/vdelivermail.c.patch-5.4.3 and patches can be generated if requested. If more people are interested in this, we could propose a mailhost field just like in qmail-ldap to make it cleaner. Here is the brief setup instruction: For two mail servers (can be more) mail1.x.com and mail2.y.com. Any of mail servers can be MX hosts. 1] Setup vpopmail on both mail servers to host x.com as usual. 2] Add mail1.x.com as an alias to x.com domain on mail1.x.com and add mail1.x.com to VPOPMAILHOME/etc/locals 3] Add mail2.x.com as an alias to x.com domain on mail2.x.com and add mail2.x.com to VPOPMAILHOME/etc/locals 4] Set user fullname to Full [EMAIL PROTECTED] for email accounts on mail1.x.com 5] Set user fullname to Full [EMAIL PROTECTED] for email accounts on mail2.x.com All emails are routed according the setting in the fullname field and using SMTP (not like qmail-ldap). The vpopmail db needs to be synchronized between sites so mysql backend is preferred but cdb should work too. Any comment are welcomed. Hope it will solve your problem. Shouguan Lin
