Changing the IMAP Port Number
The default port for incoming IMAP connections is 143. You can change this port number, but
you’ll need to change the port number for IMAP client computers as well. Make sure you
don’t change to a port number already in use by another service or operation.
To change the IMAP port number:
1 In Server Settings, click the Internet tab.
2 Click Mail Service and choose Configure Mail Service.
3 Click the Protocols tab and select Enable IMAP, if it is not already checked.
4 Change the port number for the IMAP protocol and click Save.
If you change your mail service’s IMAP port number, you must also change the IMAP port
used by all users’ mail client software.
Working With Settings for Outgoing Mail
You can change settings that affect mail going out of your mail service, including mail that
your users send to one another. The mail service has settings for sending nonlocal mail,
sending only local mail, and suspending outgoing mail service.
Sending Nonlocal Mail
If your mail service currently allows sending only local mail, you can change a setting to allow
sending mail to addresses outside your local network, including to the Internet.
To allow sending mail outside your local network:
1 In Server Settings, click the Internet tab.
2 Click Mail Service and choose Configure Host Settings.
3 Click the Outgoing Mail tab.
4 Choose “Allow outgoing mail” from the pop-up menu, then click Save.
Sending Only Local Mail
You can set your mail service to allow sending only messages that are addressed to recipients
on your local network. This setting prevents users from sending mail to addresses on the
Internet.
To allow only local outgoing mail delivery:
1 In Server Settings, click the Internet tab.
2 Click Mail Service and choose Configure Host Settings.
3 Click the Outgoing Mail tab.
