Section 6 - Securing Your Network
Congure POP3 Server
Path: Security > Authentication > External Auth Server > POP3 Server
POP3 is an application layer protocol most commonly used for e-mail over a TCP/IP connection. The authentication
server can be used with SSL encryption over port 995 to send encrypted trac to the POP3 server. The POP3
server’s certicate is veried by a user-uploaded CA certicate. If SSL encryption is not used, port 110 will be used
for the POP3 authentication trac.
The wireless controller acts only as a POP3 client to authenticate a user by contacting an external POP3 server.
This authentication option is available for IPSec, PPTP/L2TP Server and Captive Portal users. Note that POP3 for
PPTP / L2TP servers is supported only with PAP and not with CHAP / MSCHAP / MSCHAPv2 encryption.
