I am using Thunderbird 17.0.6 on Windows 7 x64. I use it to manage two e-mail accounts. I wanted to unsubscribe from a mailing list, so I sent an e-mail to an automatic service in order to do so.
I selected the address that was subscribed in the from drop-down menu in Thunderbird's "write" window.
Quickly after sending the message, I received an error on my other e-mail account saying that I couldn't unsubscribe since that account wasn't subscribed (it's not).
Why does this happen? Why did the mailing list manager interpret my e-mail as sent from another address than the one chosen in the from field?
Note: I didn't edit my
reply-to account settings.
