Comment 2 for bug 744001

hmm, this seems quite complicated to do a simple thing. Maybe people never do this, in which case I can struggle with that myself, but it seems other mailers make this simple. Perhaps an approach could be to use the Delivered-To header (if present) for the From field so long as it is in a vm-valid-mail-sending-addresses list. If it is not present (delivered-to header or valid mails variable), simply do the default which is not adding a from header.

This is more from the accessibility point of view, its a little clunky seeming to rely on external packages to do these seemingly simple everyday things. For more complicated on the fly actions pcrisis (or custom hooks) may be suitable. I also wonder whether profiles would strictly be necessary. Virtual folders, auto-folders etc are already equipped to handle this (based on headers). Maybe I'm overlooking other profile based actions that are like this and would be desirable.
