i have configured my email server to catch all mails to my mailbox. So email@example.com, firstname.lastname@example.org go to one mailbox. Every forum, registration and guy get its own address for sending me mails. So i can deliver it to /dev/null if anyone start spaming. Thats the working setup.
Now the problem: If i reply to a message, then thunderbird set always my default Identity as sender. I know i can add addidtional Identities, but i don't want to add every address.
How can i configure when a email is send to email@example.com i answer with firstname.lastname@example.org
Thanks for help
