Dear support,

I have a POP3 roundtrip sensor and it's red all the time. It shows the error: Checking for Messages: Maximum Trip Time exceeded (giving up)

I set the Maximum Trip Time (sec) to 600, 800, and the sensor continues red with same error. I did the test manually, and there is no delay when delivery and receipt of e-mails.

Could you please help me?

Kind regards and thanks,

Natasha Cunha.

What is the Maximum Trip Time (sec) setting, within the sensor's settings, defined as?
