I make generous use of qmail extensions (e.g., [email protected]). These extensions are not used by qmail for mail delivery — all mail goes to the [email protected] mailbox. However, the extension is still present in the To: address.
When replying to such mail, I would like the From: address to echo that original To: address. Thunderbird allows me to override the From address, but I need to remember to do that — not a good bet.
Is there a way for Thunderbird to automatically use the To address in the response rather than the address configured for the user at setup?
As far as I know, the only feature that may reduce your effort, are identities (http://mzl.la/1BsOxfw) if you only have a few qmail extensions (at least you can choose from a dropdown menu instead of typing the e-mail address every time, plus you can automatically sort these emails accordingly then if you like).
