Making an announcement email list+discussion
I think the problem is with the *to and *from fields. Wagn isn't capturing postfix errors very well yet. Sigh.
This isn't very well documented on the flexible email card yet, but I think if you want to use a reference (like an inclusion), then you currently have to use a Pointer card. So if you change the +*to card to a Pointer and get rid of the brackets, that may fix it.
