Messages Being Audited by IT Departments #email #issue

 

Good morning:

The group that I help own/moderate is for Law Enforcement personnel - to share info on cases, develop suspects, etc. Recently, one of the departments stated that they were having problems with messages being held up in their firewall for auditing - causing delays. Sometimes, they experience getting replies to initial emails before the initial message comes through.

Here is the e-mail he sent to me this morning. Can anyone help:

Hello ¨C most emails that are coming from @groups.io are being sent to our sandbox for virus auditing.? We use the products FortiMail and Office365.? We tried whitelisting the domain @group.io but that isn¡¯t working.? Are you able to provide a list of IP Addresses and Header information so we can try adding those exceptions?? We see many emails that users are getting replies before the original email because they are continually caught in our sandbox.? Any information you can provide as to Whitelisting by email headers, bypassing clutter and spam filtering by email header and adding @groups.io mail servers to our SPF records would be greatly appreciated!

?

Thank you,

?
 

Nicole,


Any information you can provide as to Whitelisting by email headers, bypassing clutter and spam filtering by email header and adding @ mail servers to our SPF records would be greatly appreciated!

I'm a little surprised that the department's mail administrator is asking for this information, it would already be available in the headers of messages that have been caught in his sandbox. But maybe for privacy reasons he/she's not allowed to access the content of messages caught there.

Whitelisting the as the header From domain wouldn't work reliably, as most messages are passed through with the posting member's domain in that header field (but this does vary by the member's email service).

If you receive group messages as individual emails then you (or an affected group member) could send the administrator a copy of the full headers of an example message. That should contain the information they're asking for. How to copy the full headers of a message depends on your email service or client application.

Or, send him/her this info:

The IP address for 's outbound mail server is 66.175.222.12, that should already pass his inbound SPF check. Here's what Gmail had to say about your message in my Inbox:
Received-SPF: pass (: domain of [email protected] designates 66.175.222.12 as permitted sender) client-ip=66.175.222.12;
Authentication-Results: ;
       dkim=pass header.i=@ header.s=20140610 header.b=WfNqHW7i;
       spf=pass (: domain of [email protected] designates 66.175.222.12 as permitted sender) smtp.mailfrom=[email protected];
       dmarc=fail (p=NONE sp=NONE dis=NONE) header.from=
