‘Mail’ (known as ‘Apple Mail’) is the inbuilt email client app of Mac OS X that runs on SMTP, POP3, and IMAP Protocols and therefore, it enables you setting up a Gmail, Yahoo, AOL, MobileMe or an Exchange account and access your mailbox right through the desktop. The Mail app features setting up multiple email accounts simultaneously with easy switching between them. Apple Mail stores all email messages in a single file in /Library/Mail folder.
