As most spam comes with fake sender and recipient names, this extension lets you see the email address in addition to the name. This really helps figuring out what's real and what's spam, and allows for quick sorting by sender or recipient address. I just need it to be TB 3 compatible now... Thanks!
Another simple feature that SHOULD be standard for safety reasons. Since I own my domain I create forwards for every site that requites an email address. This way I can trace the SPAM to the original culprit. Thunderbird only shows the address that the mail has been forwarded to. This shows me who stole it so I can eliminate that SPAM source. Thank you so much!!!
I've had this addon so long I'd forgotten it wasn't built-in. Sorry but I've been around the internet too long I guess. If you can't see the sender's e-mail address until after you open the mail, you can't protect yourself from spam. I don't see how it's possible something so basic has escaped TB's developers for so many years. Without this addon working I'll be downgrading back to TB 2.x .
I haven't tried this version, but the 0.0.5 you can download from the help link : http://www.moritz-abraham.de/de/programme/show-address.html
Just installed it with thunderbird 22.214.171.124 and so far haven't seen any errors, and it does what it promises, on folders containing several thousand emails. Been looking for this for a while. 5 stars from me!
Resolves a long standing issue with TB not showing full email addresses in mail list. Simple and easy to use. More flexible than Show InOut. Unfortunately neither is currently available for 126.96.36.199 yet. Hopefully soon...
