POP3 servers
FortiOS can authenticate users who have accounts on POP3 or POP3s email servers. POP3 authentication can be configured only in the CLI.
To configure the FortiGate unit for POP3 authentication
config user pop3
edit pop3_server1
set server pop3.fortinet.com
set secure starttls
set port 110
end
Each FortiGate unit can access a maximum of 10 POP3 servers. Security can use STARTTLS or POP3S protocols, or be set to none for unsecured access.
To configure a POP3 user group
config user group
edit pop3_grp
set member pop3_server1
end
A user group can list up to six POP3 servers as members.
