1781814 - Replying on mailing lists sets my FROM field to the mailing list address when using multiple identities

Status: UNCONFIRMED

(Thunderbird :: Account Manager, defect)

Description

[ehauck]

Steps to reproduce:

• Setup multiple identities (let's say [e-mail], [e-mail], [e-mail])
• Use the "Reply from this identity when delivery headers match" option on some of the identities

Actual results:

When answering to mailing lists (where none of my addresses is in the TO field) the mailing list address is chosen instead of one of my identities. This does not happen when the "Reply from this identity when delivery headers match" option is not used or just a single identity is used.

Example and details:
Let's assume the email was sent to the mailing list is [e-mail] without any other recipients. When I press Reply or Reply-All, Thunderbird sets the FROM field to the mailing list (i.e. [e-mail]), which unfortunately doesn't make sense. It displays the error message

"A unique identity matching the From address was not found. The message will be sent using the current From field and settings from identity <<matched identity>>".

Here, Thunderbird actually finds the correct identity as setup via "Reply from this identity when delivery headers match" as it is displayed instead of <<matched identity>> in the error message.

Expected results:

As Thunderbird already finds the correct identity, it should use this. If it can't match anything, it should use the default identity. This would resemble the behavior of the single identity case in my opinion.
