This article has been archived and is no longer updated by Apple.
Advanced accounts preferences

Use Advanced accounts preferences to set options related to turning on an account, retrieving messages, and keeping content for offline viewing.

Option Description

Enable this account

Make an account active or inactive. If you disable an account, Mail considers it to be offline; all of the account's mailboxes and messages are hidden from the Mail viewer window, and account activity stops, until you enable the account again.

Include when automatically checking for new messages

Specify whether you want Mail to automatically retrieve messages for this account from the incoming mail server. This option can be useful for excluding message retrieval, such as if you have an account you use only occasionally.

Compact mailboxes automatically

Specify whether to permanently erase deleted messages automatically from a mailbox or to keep them until you manually erase them.

This option is available only for Internet Message Access Protocol (IMAP) accounts that do not move deleted messages to the Trash mailbox (as specified in the Mailbox Behaviors pane).

Keep copies of messages for offline viewing

Specify whether to keep copies of messages or attachments on your computer so you can access them when you’re not connected to the mail server.

It’s recommended to use the default selection (“All messages and their attachments”) so you can search entire messages. Additionally, keeping copies of messages on your computer improves junk mail filtering and includes the messages in Time Machine backups.

This option is available only for IMAP and Exchange accounts.

Remove copy from server after retrieving a message

Specify when you want to delete received messages from the mail server. You can deselect this option if you need to temporarily access messages from more than one location or computer.

This option is available only for Post Office Protocol (POP) accounts.

Prompt me to skip messages over x KB

Specify the maximum size of messages you want to retrieve automatically, such as 100 KB. This option is useful if you want to retrieve large messages later or when you have a fast connection to the mail server.

This option is available only for POP accounts.

IMAP Path Prefix

Specify the location of your mailboxes on an IMAP server. Use this option only as directed by your system administrator.

Internal Server Path and External Server Path

Specify the paths for the Exchange Web Services server for an Exchange account. Use this option only as directed by your system administrator.

Port (or Internal Port and External Port) and Use SSL

Specify the port numbers to use to send messages, and specify whether to use Secure Sockets Layer (SSL) to provide a secure connection to the mail server. Use these options only as directed by your system administrator.

Authentication

Specify how you want to authenticate your identity to the server. Use this field only as directed by your system administrator.

This option is available only for POP and IMAP accounts.

Domain Name

Specify the domain name for the NT LAN Manager (NTLM) authentication method. Use this option only as directed by your system administrator.

Use IDLE command if the server supports it

Specify that the server should notify Mail when new messages are available for your Inbox. This method is known as “push email.” This option is available only for IMAP accounts.

When this option is not selected, Mail checks for new messages by connecting to and querying the server at regular intervals.
