instead of the username, I would like to use an alias address as the default 'from' address for my users.
Note that I don't want to select from my alias addresses as asked for in bug 5862, but simply to use a different default.
I tried to change the reply-to address in the user's mailbox settings, but that didn't do it. (Can someone explain to me, what this reply-to address is used for? The Documentation is not very specific about it.)
I could change the 'from' address by using the zmprov tool
as stated in Changing domains and username .
But is there a better way to do it?
