F-Secure Internet Gatekeeper uses POP and SMTP authentication on the server side. The product
works as a proxy to enable access from clients to the mail server. Therefore, user authenticating
functions based on POP and SMTP authentication by mail servers can be used as is.
To use the SMTP authentication on the mail server, disable the SMTP authentication setting for
F-Secure Linux Internet Gatekeeper. To disable SMTP authentication for the product:
•
Open the web console
SMTP proxy > Global settings and turn off
SMTP authentication
.
If you use APOP, disable the parent server setting of the product. To disable the parent server:
•
Open the Web Console
POP proxy > turn off
Defining parent server by user
.
Due to protocol specifications, you cannot use APOP if
Defining parent server by user
is enabled.
If you want to use APOP, make sure that you do either of the following:
■
Turn off
Defining parent server by user
.
You can do this in the web console.
POP proxy > Defining parent server by user:
Off
■
Use a transparent proxy.
