If a domain name in this list does not have an MX record, only your mail service recognizes it.
External mail sent to this domain name will be returned. You should place domain names
without MX records in this list only as a time saver for local (internal) mail.
Changing Protocol Settings for Mail Service
You can change the settings for all protocols that your mail service uses. These may include
SMTP, IMAP, POP, and NotifyMail.
1 In Server Settings, click the Internet tab.
2 Click Mail Service and choose Configure Mail Service.
3 Click the Protocols tab, then click the Options button for the protocol you want to change.
4 Make the changes you want and click Save.
Monitoring and Archiving Mail
You can configure mail service to send blind carbon copies of all messages to a user or group
that you specify. You might want to do this if you need to monitor or archive messages.
Senders and receivers of mail do not know that copies of their mail are being archived.
You can set up the specified user or group to receive the blind carbon copies using POP, and
then set up a client email application to log in periodically and clean out the account by
retrieving all new messages. You may want to set up filters in the email client to highlight
certain types of messages. Or you may want to archive all messages for legal reasons.
To monitor or archive all messages:
1 In Server Settings, click the Internet tab.
2 Click Mail Service and choose Configure Mail Hosts.
3 Click the Incoming Mail tab.
4 Select “Blind copy incoming and outgoing messages to” and type a user name or group
name.
5 Click Save.
Working With Settings for Incoming Mail
You can change settings that affect mail coming to users of your mail service, including
mail your users receive from one another. The mail service has settings for limiting incoming
message size, deleting incoming messages automatically, and notifying users who have
new mail.
