I am fetching from multiple users and ISPs on the source end and feeding a 
single user on the local destination end. The second ISP, earthlink, does not 
use SSL. A second fetchmail is running in another user's account that is not 
showing this problem because it is not using SSL, either.

I have tried two configurations:
Originally
poll mail.dslextreme.com with proto pop3 port 995
     user '[email protected]', with password 'xxxxx' ssl,
     is 'jdow@lllllll' here pass8bits
poll mail.dslextreme.com with proto pop3 port 995
     user '[email protected]', with password 'yyyyyyy' ssl,
     is 'jdow@lllllll' here pass8bits
poll pop.earthlink.net with proto pop3
...
And the second one comments out the second poll line in the above:
poll mail.dslextreme.com with proto pop3 port 995
     user '[email protected]', with password 'xxxxx' ssl,
     is '[email protected]' here pass8bits
#poll mail.dslextreme.com with proto pop3 port 995
     user '[email protected]', with password 'yyyyyyy' ssl,
     is 'jdow@lllllll' here pass8bits
poll pop.earthlink.net with proto pop3

Both show the same problem. And the --configuration printout appears to make 
sense to me.

These look suspicious in the first printout:
fetchmail: mail.dslextreme.com: WARNING: server offered STLS, but sslproto '' given.
fetchmail: POP3> USER [email protected]

In the current configuration it looks like the YYYY ID was not polled, too.

The per item 5 log shows the JkiO mail being sent.

No, the computer has not been rebooted.

This MAY be related to the ISP changing over from DHCP connections to PPPOE. But 
I don't see how the MTU change that brings to the table would change things. The 
earliest illegal address log entry I found is more than a year old. So whatever 
triggered it a few times over a couple years is now triggering regularly.

I did go ahead and reinstall fetchmail. And, indeed, that is the version of 
fetchmail that is current in CENTOS and Scientific Linux. (I'll likely be 
gritting my teeth and moving over to CENTOS since SL is not moving on to RHEL8 
clone status.) The version is currently 7.6.
