Thanks a lot
I'm currently too busy to set up a test system to work out the details, but I'll outline the thought I had so that you might look into it. The normal way in which I have systems forward mail to a smarthost is having them log in via SMTP AUTH (over TLS) using a separate login name for each machine. The client.passwd file contains a list of lines that look like: mailserver.example.net:Grumpy:BadPassword When you set a particular smarthost to send mail to, that's usually using a 'manualroute' router, but the manualroute router has options to allow using a /list/ of machines to send mail through for a particular domain via the route_list option. Between these two features you should be able to send mail through another smarthost if the primary one is down -- automatically. At least, that's the theory. -- Chris -- Chris Knadle [email protected] -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
