Sysadmnpro Does not display 50 lines of mail log

I purchase the sysadm module, and attempted to configure my email server. However; I have been unable to send or receive emails. In addition, the module when running debug, does not provide the 50 lines from the mail log. I am required to go to the command prompt and use the tail command for the log. Am I missing something or is this a module error?

Thanks for the assistance in regards to this matter.
