Hello everyone - I did some more poking at this last night, and I think I have devised a work-around. The basic process is to have logwatch output a file and then call s-nail from a script to send the file.

Step 1 - Add these lines to /etc/logwatch/conf/logwatch.conf:

Filename = /temp/logwatchreport.txt Output = file

Step 2 - Create a shell script named /usr/local/bin/sendlogwatchreport. It simply a call to s-nail:

/usr/bin/mailx -m /temp/logwatchreport.txt \ -s "Logwatch report for centos7.billgee.local" \ -r logwatch@centos7.billgee.local \ --batch-mode \ bgee@campercaver.net

The "-m" parameter takes the named file and makes it the body of the email message. Note that the default logwatch call to a mailer uses the "-t" parameter which expects the input to be a template. The template includes lines at the top which are turned into the email headers for subject, to and from fields.

Step 3 - Modify /etc/s-nail.rc. This line is changed:

set asksend changes to unset asksend

Without this s-nail gets stuck waiting for user input that will never come.

Step 4 - Add the shell script to the cron.daily list of tasks. I did this by creating a hard link.

ln /usr/local/bin/sendlogwatchreport /etc/cron.daily/sendlogwatchreport

More testing is required for this. I think there are some permission problems. I tried to use the /tmp directory, but files that logwatch puts there disappear before the script can use them. Creating /temp with 777 permissions is an attempt to work around this.

When run from a root prompt, logwatch and sendlogwatchreport result in a nicely readable email message. I am not sure what will happen when anacron runs the process. It will take an overnight cycle to find out.

It is called "Quoted Printable". There should be something in the E-Mail header that indicates this (Content-Transfer-Encoding header). Maybe either Logwatch or s-nail is leaving out this header.

=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.
