I wanted to have the logwatch cron results mailed to me instead of root so I edited /etc/logwatch/conf/logwatch.conf to add this line: MailTo=SBlackwell Just for a sanity check $ whoami SBlackwell $ uname -n mylocalmachine <not really but just to show I checked that it matches the mail message> but root keeps getting returned mail saying <snip> ----- The following addresses had permanent fatal errors ----- sblackwell (reason: 550 5.1.1 <sblackwell@mylocalmachine>... User unknown) (expanded from: sblackwell) <snip> The thing that stikes me is that my user name got changed from SBlackwell in the conf file to sblackwell in the mail message. Anybody else seeing this? Any comments? Steve
