Setting Mail Preferences in iCloud
Use Mail’s Preferences to customize how you see your messages and how your mailboxes behave. You can also create alias accounts, as well as automatic response messages to let people know when you’re unable to read or respond to e-mail.
Click the Action button, select Preferences from the pop-up menu, and then do the following:
General: Select the check boxes to control how you see your messages and change the destination for sent and deleted messages. Take note of the Forwarding option. You can forward your firstname.lastname@example.org mail to the e-mail address you use with Outlook or another preferred e-mail client so you receive your iCloud mail there. (The alternative is to not give your iCloud e-mail address to anyone and use iCloud only for synching contacts and calendars with your Windows PC and iOS devices.)
Accounts: iCloud permits you to create up to three aliases, which are an excellent solution for message jam. For example, you can use your iCloud e-mail address for personal or business correspondence and then set up an alias for e-newsletter subscriptions. To create an alias, do the following:
Click the Accounts icon at the top of the Preferences window.
Click Add an Alias at the bottom of the account list.
Type a name for your alias, choose a label color, and then type a description.
Click OK. If your alias isn’t available, a message tells you so. You have to try a different name; click OK again.
Your alias account appears in the accounts list.
Composing: Choose how your outgoing messages appear and create a signature line.
Rules: Mail can automatically file, delete, or forward messages for you based on the recipient or subject. Navigate the Add a Rule pop-up menus to make your selections.
Vacation: When this preference is active, a response (which you write) is automatically sent to every incoming message.
Some actions, such as creating aliases or making rules, can be performed only from your computer in Mail on your Mac or at iCloud.com although they take effect across all devices.
