My /var/log/.exim4/log file is flooded with messages such as shown
below. I'm not trying to send mail to any of those .co or .com
addresses. I use my ISP (shaw.ca cable provider) as a smarthost.
Are people trying to use my system as a relay? If so, can I block them
without cutting myself off from remote access to the IMAP server I run
on my system?
Sorry if I sound lame. I set this up over 20 years ago and haven't done
anything to it since.
