Personally, I am a lot more annoyed by the incessant complaints about “top posting” on mailing lists than the actual top posting itself, especially on the postfix-users list: Is it really necessary to address these complaints to the list at large and quote the entire original message text when doing so? Also, the layers of multiple quoting, and lack of appropriate trimming of quoting, are frankly ridiculous at times. So, I sought out some Thunderbird extensions that help to make mailing list posts easier to read and digest.
