Why are we getting Authentication Failed, and Socket Error 10060, from our IMAP Sensor



We are monitoring several backup services within one mailbox. All of the backup services send emails to one email account. We followed the instructions given for the previous question


We have seen "authentication failed errors and socket Error 10060" with office360,

We have seen "connection timed out" errors with our actual email address.

We login to the account via Office365. Our domain Host did see a "No MX record for the domain" notice.

We do have Clowd Flare configured to prevent denial of service attacks.

This is a lot of moving parts. Do you have any suggestions?

That's indeed many potential error sources...did you try to cycle between the security settings of the sensor already to see if either of them works?
