Here are some more ways to do the same thing:
1. Create a group "example"
2. Create 3 local users, all configured to forward to off-site addresses (as specified), and add all 3 to the group.
or
1. Create a user "example"
2. Manually modify /home/e-smith/files/users/example/.qmail to include multiple forward lines (you'll need to figure out how to template this eventually!)
or
(Works, but you won't be able to use server-manager to edit this user afterwards, and you'll probably break something else, too!)
1. Create user "example"
2. run the following commands at the command prompt:
db accounts setprop example EmailForward forward
db accounts setprop ForwardAddress "userone@gmail.com\n&usertwo@lycos.com\n&userthree@yahoo.com"
signal-event user-modify
(Note: when setting properties in any of the configuration databases, upper/lower case, punctuation, etc. are extremely important!)
less /home/e-smith/files/users/example/.qmail
will show you what's been done to the .qmail file for "example"
or
Install the qmail dot-forward package, and template the users' .qmail changes necessary to use it.
or
Install the qmail fastforward package (and template the users' .qmail changes necessary to use it.)
Summary
There are lots of options, but the mailing list contrib is probably the easiest. If you've tried it and for some reason it is unacceptable, try one of these...
