Created attachment 1507 [details] Example patch RFC#4155 defines the mbox format, and the "From " line must have the UNIX 'ctime' formatted UTC date. So it should be: From - Wed Apr 15 22:04:35 2015 instead of what is used currently: From - Thu 16 Apr 2015 00:04:35 CEST Due to the "From " separator philosophy, mbox processing tools need to be careful to not accidentally split on non-separator "From " lines. Therefore, many tools are very picky on the format of the "From " line. Using local time instead of UTC is acceptable, though. An example patch is attached.
