When clicking on hyperlinks that are set to open a compose email message on OSX the Mail.app application will launch. Since it is likely that your preferred email application is something other than Mail.app such as Mozilla Thunderbird, Opera, Microsoft Outlook for Mac, Postbox, Sparrow, or something else then you will want to change the default email client to your preferred email application. In my case I use MS Outlook for the Mac so I needed to set the default email client to Outlook. Use the directions below to modify the default application that opens to compose email messages.
While working on a clients Ubuntu Linux computer I needed to send some of the logs to myself so I could analyze them at a later date but there was not an SMTP server installed on the computer. This can be resolved by installing the Exim MTA (Mail Transfer Agent) using the below apt-get command which is actually stated fairly clearly in the output of attempting to use the mail command from the Ubuntu CLI as shown below. The initial attempt at using the mail command as well as the output from apt-get is displayed in the below example output.
