Indeed, if an articles has a line with a single dot « . », it is well displayed the first time I see the article. But it is saved to the disk, in the Thunderbird newsbox, as « .. ». Then, if I reopen Thunderbird and read the article (locally saved), it displays « .. » (and not « . », as I still can see in the source of the article [Ctrl+U]). Reproducible: Always I believe Thunderbird should always save the article in its own format (and not in wireformat when the article is sent in this format).
Why, so it does. (I just put a couple sample messages in mozilla.test, but it's plenty easy to reproduce.) I'm refiling this under MailNews:Backend; there is a MailNews:Offline component, but it's located under Suite rather than Core. Note: it's not possible to View|Message Source for an offline news message -- but there's already a bug for that, bug 128297.
This looks like bug 170727 to me...
I agree, duping. *** This bug has been marked as a duplicate of 170727 ***
