New issue by xelxebar on mblaze repository https://github.com/leahneukirchen/mblaze/issues/176 Description: Admittedly, this is a strange thing to do, but as a workaround for while #173 is in the works, I have been calling mrep like this: $ mrep -from "$(maddr -h from .)" Which ends up creating two `From` headers, one with the value from the command above and another with the `local-mailbox` address. A few times I've slipped up and forgotten to delete the spurious `From` header, which usually ends up causing bounces. Anyway, is this something worth fixing?
