Steps to reproduce:

  • Setup multiple email addresses (let's say a@foo.com, b@foo.com, c@bar.com)
  • In Account Settings, activate "Reply from this identity when delivery headers match" and set the value of the field to "*@foo.com"
  • Have a mailing list from "foo.com", say mailinglist@foo.com

Actual results:

When someone sends a mail from x@foo.com to some person somebody@foo.com, and puts the mailing list mailinglist@foo.com in the CC field, when replying either to the sender or the mailing list, Thunderbird choses the email address of "somebody@foo.com" as the sending mail address, and not my address a@foo.com.

Expected results:

My identity a@foo.com should be the sending email address, and not some third party, of whom the identity was stolen.

OS: Unspecified → Linux
Hardware: Unspecified → x86_64

But then you should uncheck the "Reply from this identity when delivery headers match". It's really primarily meant for cases where you own the domain and don't want to set up identities for everything.

Summary: Thunderbird impersonates other email address when replying to a mail whose CC is a mailing list → Thunderbird impersonates other email address when replying to a mail whose CC is a mailing list (with catch-all)

Thank you for your quick reply. I see why the behavior is what it is. But I believe the phrasing and purpose of this option should be clarified.

I (mis)took "this identity" to refer to a@foo.com in our example, and the whole option to mean: if someone writes me with an address of whatever@foo.com to my address at a@bar.com, Thunderbird will by default choose my address a@foo.com as reply-identity, and not a@bar.com. (which could be an useful option to have, btw).

Could the prompt maybe use the following phrasing: "Reply from addressee identity when delivery headers match (only use this in cases where you own the domain and don't want to set up different identities)" or something similar ?

Hi Gerhard, thank you for sharing your experience with this feature.
It's indeed quite possible and easy to take the label literally and thus misunderstand it as in your example.

  • I'd agree with you that the label isn't quite descriptive enough, and would probably need an in-product link to more information.
  • Unfortunately, there's no documentation either yet. Relevant articles:

Are you able to test bug 1781814 and see if that also happens as described?

Duplicate of this bug: 1811758

Well, OK, I hear what you are saying that the feature doesn't actually do what I thought it did from reading the description of that checkbox.

And maybe what the feature actually does is useful and intentional.

But separately from that I would really like the feature I thought it was to actually exist. I.e., I don't want TB to impersonate an email address in the To line of the message when sending a reply; I want it to use the email address associated with the identity when replying to any message sent to any address in that domain.

E.g., as noted in bug 1811758, if I have an identity jik@extended-thunder.org, then I want to be able to say, "Whenever anyone sends email to an address in the extended-thunder.org domain and I reply, use jik@extended-thunder.org as my reply address." Which is the behavior I expected from the string next to the checkbox.

In any case I will turn off the checkbox for my identity at least for now since it very much does not do what I want it to.

I am not able to reproduce bug 1781814. When a mail is sent only to a mailing list from the same domain my mail address is from, I directly see the options

  • reply
  • reply list

When using either of those, the sender address is set correctly to my individual address. "Reply list" allows further to choose several options, namely:

  • Reply list
  • Reply all
  • Reply

In all cases, the sender address is set correctly to my individual address.

NB: I did activate the option "Reply from this identity when delivery headers match", and restart Thunderbird. I did not restart the computer. If this is something you believe might change the outcome, please let me know.

Flags: needinfo?(gerhard.schaden)

I'm the author of bug 1781814 and want to add a detail. We hardly use real mailing lists, more "mail dispenser lists", i.e. there's one address that gets forwarded to various people without any moderation. Not sure if that changes anything, but at least I thus don't have the option "Reply list".

But I can still reproduce my described behavior with Thunderbird 102.4.2 by setting the the option "Reply from this identity when delivery headers match" without even restarting Thunderbird.

P.S.: As the bugs seem at least very strongly correlated, I answer here instead of my bug report. If you like to have that differently, please tell me.
