Warning
Precautions must be taken when configuring the mail server, otherwise you become
susceptible to such abuse as unauthorized relaying of unsolicited email (spam) using
your server. Configuration of the email server is outside the scope of this manual.
Where possible, add packet filter rules to restrict access to the internal email server to
trusted external hosts only.
First, add a service group to group email services (SMTP, POP3 and IMAP).
Click Definitions, the Service Groups tab, then New.
Enter E-Mail in Name.
Check one or both of IMAP4 (E-Mail) if your server supports IMAP mail retrieval and
POP3 (E-Mail) if your server supports POP3 mail retrieval.
