New comment by nmeum on mblaze repository https://github.com/leahneukirchen/mblaze/pull/173#issuecomment-606149621 Comment: > Well, I have some private addresses that are listed as Alternative-Mailboxes to get the sign, but that I don't use for replying. It would certainly be possible to add a new `auto-reply-addresses` profile header setting (or something along the lines). > Also, people could use From: addresses that are not in Alternative-Mailboxes (e.g. a shared helpdesk email). Why would that be a problem? Unless I am missing something here the code should fallback to `local-mailbox` then. If you generally disagree with the feature I will just apply my patch locally. If you like the idea in general but don't like the implementation I can try to adjust it. Either way is fine with me.
