Password of the Day for Hotspots

Hello Everyone,

 

So it seems we are facing a new issue. Up to now we haven't experienced any issues with the Password of the day function for Sophos. Currently, we have an SG105 in place at a client. I noticed after awhile that no emails were getting sent. Since then I realized that it, the firewall, will send to any emails such as self-hosted, etc. However, it will not send an email to any Office 365 accounts?!

 

So far we have messed with whitelisting, spam filter, rules, and looked through other settings in Office. We contacted a Sophos rep who didn't seem to know what to exactly do. The most information I could find was when I performed a message trace and received the following

 

"Office 365 received the message that you specified, but couldn't deliver it to the recipient (****.com) due to the following error:

Error: 550 4.3.2 QUEUE.TransportAgent; message deleted by transport agent

A non-delivery report (NDR) message was sent to *sender*. The NDR might provide more details about why the email message wasn't delivered and how to fix the issue."

 

 

I really hope someone can help with this. It would be great to figure this out so we can document it for the future!!

Thanks,

Mike

  • Hi Mike and welcome to the UTM Community!

    What if you whitelist or skip anti-spam for do-not-reply@fw-notify.net in Office 365?

  • Hi Bob,

    Thanks for the suggestion. I went through and added the fw sender address to both of the above-mentioned items. Unfortunately, that did not work for me. I'm still a bit puzzled as to what it could be. I'm still receiving the password at the specified times on our accounts from the exchange server but nothing office 365 is getting them.

     

    Thanks,

    Mike

  • What happens if you telnet to your MX record from your UTM and have an SMTP conversation with it?  My guess is that it will still reject you as spam.
