New email issue....
I recently ran into a email issue. Im not able to send or receive emails to from my perfectly set up Ubuntu box. I have been running ISP config for months now, and was using it as a mail server without issues until today. How can I troubleshoot the error effectively to narrow down possible errors. I reviewed the mail.log file in the var/log directory, nothing poked out at me... however, I might not really know how to read it. Any help would be most appreciated!! Thanks in advance.
