Configuring Incoming Mail Service | Apple 10.6 guide

Saving Mail Messages for Monitoring and Archival Purposes

You can configure Mail service to send a blind carbon copy (Bcc) of each incoming or outgoing message to a user or group. You might want to do this to monitor or archive messages. Senders and receivers of mail don’t know that copies of their mail are being archived.

You can set up the user or group to receive Bccs using POP, then set up a client mail application to log in periodically and clean out the account by retrieving all new messages. Otherwise, you might want to periodically copy and archive the messages from the destination directory using automated shell commands.

You can set up filters in the mail client to highlight types of messages. Additionally, you can archive all messages for legal reasons.

To save all messages:

1In Server Admin, select a computer in the Servers list, then select Mail.

2Click Settings.

3Select the General tab.

4Click the “Copy all mail to” checkbox and enter a user or group name.

5Click Save.

Configuring Incoming Mail Service

When configuring incoming Mail service, you configure mail to be retrieved by users and mail client applications. It involves these basic steps:

ÂÂ Choose and enable the type of access (POP, IMAP, or both). ÂÂ Choose a method for authentication of the mail client.

ÂÂ Choose a policy for secure transport of mail data over SSL.

The following sections explain how to enable IMAP and POP access. For information on authentication and SSL, see “Securing User Access to Mail Service” on page 62.

Enabling IMAP Access

IMAP is a client-server mail protocol that allows users to access mail from the Internet. With IMAP, mail is delivered to the server and stored in a remote mailbox on the server. To users, mail appears as if it were on the local computer.

A key difference between IMAP and POP is that with IMAP the mail isn’t removed from the server until the user deletes it. IMAP connections are persistent and remain open, maintaining load on the server and possibly the network as well.
