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:
================== =20 ################### Logwatch 7.5.5 (01/22/21) ####################=20 Processing Initiated: Thu Jan 19 13:31:57 2023 Date Range Processed: yesterday ( 2023-Jan-18 ) Period is day.

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.
