What does the error message Unable to get canonical name of client mean?
This error message in your log means that a client connected in and Qpopper got an error when it tried to do a reverse lookup on the IP address. If the client is local, this may indicate a problem with its DNS entry (specifically the PTR record for that IP address), or it may be a temporary DNS problem. Qpopper allows you to turn off this check if you like. Qpopper also includes the IP address of the client in the log message, to make it easier to check its DNS entries.
