Today I decided to get rid of a small thing that has been annoying me for a while. On Mac OS X, because it is BSD UNIX based it has a local mail delivery agent, specifically Postfix. Whenever your computer has messages it needs to send to you it delivers them locally to /var/mail/SHORTUSERNAME This is all well and good, however unless your a Terminal user you'd never know you had any mail, and even if you happened to open the terminal and got the prompt "You have mail"
Once I took a second to think about it I did the following: change the file /private/etc/postfix aliases and include an entry for your local account shortname and enter the external email address you wish your mail to goto. run postalias hash:/private/etc/postfix/aliases then newaliases
Thats it. now mail destined for your local account will get sent to your normal email inbox.
