In the middle of normal text some lines or even whole blocks starting with "From" show up as quotation (arrows in front of, etc.) and also behave as such (no line wrapping as does the normal new text, etc.). This problem exists at least since the Netscape/2 4.xx mail client. Reproducible: Always Steps to Reproduce: 1.Compose a (plain text) mail message containing for instance the line "From France with Love" (no quotes) 2.Send (later) or save the message. 3.Look at it in the folder where it got copied to. Actual Results: The lines containing the "From" word followed by more text show up as quotation. Expected Results: It should have shown these lines or paragraphes as normal (un-quoted) text just like the other lines not starting with "From". The browser used at this time has the default theme, and has only few extensions installed. Linky, Dutch language scheme (not active in this profile), middle mouse button scroll. The bug has existed for many years, thought it about time to report the problem. :-) about:buildconfig Build platform target i386-pc-os2-emx Build tools Compiler Version Compiler flags gcc gcc version 3.2.2 (Innotek Build 2003-10-06 19:38) -Wall -W -Wno-unused -Wpointer-arith -Wcast-align -Wno-long-long -pedantic -Zomf -pipe g++ gcc version 3.2.2 (Innotek Build 2003-10-06 19:38) -fno-rtti -fno-exceptions -Wall -Wconversion -Wpointer-arith -Wcast-align -Woverloaded-virtual -Wsynth -Wno-ctor-dtor-privacy -Wno-long-long -pedantic -Zomf -pipe Configure arguments --disable-debug --enable-optimize --enable-crypto --disable-profilesharing ************************************************************************** Thanks for looking into this and more thanks for providing us with such a marvellous multi-purpose product!

Well, I am not suggesting that Slashdot is authoritative, but it does cover the news, and it may be news to people who come to this bug that most (if not all) Mail Agents quote (escape) the word From appearing at the start of a line. The article gives a lot of other background information, links to RFC's and various comments on the topic at hand, some of which are (like the OP) critical of this practice and the also the fact that it is non-obvious. This was the best I could find quickly, given that Google cannot be expected to come up with much on the word 'From'. Now, what about the word 'epyhda'.

I am not sure which one is the correct on to dupe this to, it's either bug 121947 or bug 194382. Because the latter explains about the shortcomings of the mbox format I use that... *** This bug has been marked as a duplicate of 194382 ***
