POP3 Proxy don't filter mail traffic

Yann LEDUC

Hi,

I have a problem with my UTM9 ng135

it is configured for several months but since the 17/10 8:00 p.m. it not filter any email.

I tried to restore a configuration to an anterior date, but this does not resolve the problem.

The configuration very simple, we can not make any mistakes.

The mail server is outside the house, at a hoster.

The only point would be a road or a rule to create?

Is one of you has already encountered this problem?

Thank you in advance for your answers
 
Best regards

    Yann, configuring the POP3 Proxy is one of the more-convoluted processes in WebAdmin and it's easy to miss a step.  You can't solve this problem with a static route or a firewall rule.

    When you say it's not filtering email, what do you see that leads you to that conclusion?

    What happened at 20:00 on 17 October, and how did you determine the exact time?

    Can you confirm the 'Advanced' tab is setup correctly by pinging the FQDN of the server listed in 'POP3 Servers and Prefetch Settings'?  Is 'Use prefetch mode' selected?

    Does the 'POP3 Accounts' tab in the User Portal have correct and complete information?

    Once you've confirmed all of the above, login to your server with your POP3 Client, open an email and then logout.  Did that start the filtering process again?

    Cheers - Bob
