New issue by xelxebar on mblaze repository
https://github.com/leahneukirchen/mblaze/issues/233
Description:
## Overview
Commit e1e5bfe5 introduces a regression against 282de650. In cases where there are multiple `Delivered-To` headers, it is most likely that we want `mrep` to populate the sender address from the most public-facing `Delivered-To`, *i.e.* the first one; however, at the moment we are setting it to the address in the final (*i.e.* topmost and most internal-facing) one.
## Why?
We have a posix setup that aliases multiple addresses into a virtual mailbox---*e.g.* all mails going to `mars.*@example.com` get glommed into `mars@example.com`. The problem is that postfix aliases end up adding an additional `Delivered-To` header for each of these alias redirections. This is necessary to detect alias loops and related problems.
## Patch points
This proposed change boils down to munging [mcom:377](https://github.com/leahneukirchen/mblaze/blob/master/mcom#L377). I believe we just need to reverse the order of headers passed to `maddr` and then `tail -n 1` instead of `head -n 1`. However, it appears that `maddr` doesn't currently have a `-M` switch like `mhdr`, so maybe a patch there is needed as well?
## Comments
Thoughts? Does the above sound reasonable?

About the use case I had, I only had one Delivered-To. If the fix continue to pick it, rather than the useless To, it is okay to me. Choosing the first Delivered-To seems okay and predictable to me

Comment:
I guess both could be argued for, e.g. if you have multiple alias expansions they'll all end up as a Delivered-To..
I agree that maddr should parse repeated headers.

Comment:
Jumping on this, I received a mail on an account I've put into my `Alternate-Mailboxes` setting but when replying to it via mrep it reverts the `From:` to default.
Is there a setting which lets me always use the `To:` address if it's inside the `Alternate-Mailboxes` setting? I couldn't find such a thing inside `mcom`.
If not, I may open a PR.
