logwatch reporting Unmatched Entries

[Robert Moskowitz]

This is a new, test, build on CentOS7, amavis-new 2.11.1

every day I see the following in the logwatch report


  **Unmatched Entries**
         1   Deleting db files __db.002,snmp.db,nanny.db,__db.001,__db.003 in /var/spool/amavisd/db
         1   (07387-01) xoFkWZwqm0CN FWD from<root at klovia.htt-consult.com>  -><root at klovia.htt-consult.com>, BODY=7BIT 250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 01E0E92C9
         1   No ext program for   .rar, tried: unrar, rar
  
I suspect the 2nd is the logwatch email, as that was the only email processed on that day.

Are any of these something I should/could something about?

thanks
