Hi Sergey (and all) - does mailutils provide utilities along the lines of mpack and munpack to create or read mime messages? I could not tell, but I did not see it. I'm sure all the functionality (and much more) is there in libmailutils, but could not find a way to access it from the cmdline.
Since m(un)pack is apparently no longer maintained, having a maintained successor would surely be welcomed by many people. The best? version I found was https://github.com/league/mpack/. All the heuristics and binhex and other ancient stuff doesn't matter (IMHO), just the basic mime pack/explode functionality. However, I probably shouldn't be asking the above; it just seemed like a good idea. What I actually want is something that I think munpack does not do: given a msg with text/* base64-encoded parts, undecode them to stdout, leaving the msg otherwise unchanged. As I'm sure you are well aware, plenty of mailers nowadays decide to useless base64-encode everything, making the messages opaque to grep etc. Sigh. Surprisingly, I could not find any scripts or recipes to do that particular job. Seems procmail has no built-in understanding of mime parts. If you have any ideas, please send them my way :). --thanks, karl P.S. At https://www.gnu.org/software/mailutils/mailutils.html#documentation "TeXinfo" should be "Texinfo". P.P.S. stylistically, the font size is being reduced on that web page for no reason I can discern. Compared to, e.g., https://www.gnu.org/software/autoconf or automake, which use the font specified by the user (me). I could not easily see what css is making that happen.
