I am working on a script which is monitoring my software raid-1 raid array and sent event mail to local mail system.
By default, Ubuntu Gutsy dose not have local mail delivery system(message transfer agent "MTA") installed. The best way is to install mutt then all the dependents( exim4.....) for MTA will be installed as well.
After mutt installed, I configured Evolution to receive local mail.
In Evolution use user name as username@localhost and chose 'standard Unix mbox spool directory' as server type.
For testing, use mutt to send a testing mail then use Evolution to fetch the mail.
