=20 is an ASCII space character, and =3D is an ascii "=" (equal) sign.

I've seen various emailed documents that mangle them as you see, but if I ever knew the cause, my tired old brain no longer remembers.

Now that I have a test CentOS9 system set up, I am trying to get it to send me logwatch reports via email. S-nail is proving very frustrating. It almost works ... But not quite!

The main problem is bogus characters in the logwatch report. Here is a section of the report I get through email:

What are all those =20 and =30 strings for? How do I make them go away?

I have been experimenting with a line in /etc/s-nail.rc.

    set ttycharset=utf-8

That is the only value for this that produces anything useful. If I set it to charset-7bit or charset-8bit, then s-nail complains about invalid syntax on the "set mta=" line. What????

I just don't get it. Can someone shed some light on this?

For what it is worth, a test CentOS8 system using mailx (the REAL mailx!) works perfectly. So do all of my CentOS7 and Fedora systems.
