[Alpine-info] Setting the postponed folder for alternate roles

[Josh Rickmar]

I have set up a role as my "mailing list account" (this account), but
when I use C-o to postpone my message, it gets saved into my drafts
folder for my main account.  I have searched through the roles
preferences, but I can not find any way to set a custom postponed folder
when using a different role.  Is this feature available?
