Change 325040 had a related patch set uploaded (by Huji):
Email footer should state that by responding one reveals their address

https://gerrit.wikimedia.org/r/325040

A non-issue as for me.

• When you send an e-mail, you reveal your address to the recipient, everyone knows that.
• And when you're composing a letter, you see the recipient's address in UI, so you know who you're revealing it to, everyone knows that, too.
• Using Reply-To: to have a reply be sent to an address other that what the original letter came from is standard practice as well.

So, I don't see what problem this intends to solve.

Yeah...you'd think that but:

Anyways, I agree with Huji on this that it seems like a safe thing to do. I did remove it as a blocker however.

It also keeps the WMF out of possible legal trouble if, say, someone finds out a user's email address using this and starts harassing that user. It's basically a disclaimer warning the user replying, so the user can't then say they didn't know their email would be disclosed. That's probably at least part of the reason the original email system included the disclaimer.

(ugh, one of the reasons I don't use web gmail)

By using a UI like that, you testify: "I don't care who my mail actually goes to."/"I (blindly) trust the sender & Google to have set up everything, don't bother me with such insignificant details."
Wikipedia isn't here to cover for deficiencies in 3rd-party software, is it. Which effectively duplicating a mail header elsewhere is.

It did? Why was it removed then?

It hasn't been yet. @Legoktm's patch in its current state would. Besides, I'm not a WMF employee, so I don't know why it was originally included. I was just giving my best guess.

What are you referring to? I can't think of any of my patches that would do that.

Yes. See https://www.mediawiki.org/wiki/Bug_management/Bug_report_life_cycle. From there:

A report is given the Resolved status when a code change that fixes the reported problem has been merged in Gerrit. This does not mean that the fix is immediately available on a Wikimedia website as it can take up to two weeks.

@Legoktm - ok thanks. Thats mean we can be sure its work after "Verified" tag being added?

The verified tag is optional, and I don't think most people use it. For this bug once it's deployed I can leave a comment here.

@Legoktm - ok - after you leave the comment here - I will test it on ru wiki. Cause I have problems with Emails.
