I hired someone through fiverr to upgrade my Ubuntu system, saving the email and webpages hosted there. He accomplished the upgrade, but not successfully. Now when I log in via PuTTY, I get a constant stream of broadcast messages from the mailserver app. I'm unable to get anything done.
Any suggestions on how to stop the messages?
ps -ef > /tmp/test.txt, but only get an empty file. If I could get that output I might be able to do a kill command.
