Expected PPD and Current Setup?

[cfhdev]

Response from Microsoft. Since the sending domain is not inside your tenant you will need to work with the senders Admin and ask them to do a message trace and see if the message is leaving the @foldingathome.org environment. You should also ask if there is a delivery failure that they can reference. We need to see if it is leaving their environment and being rejected by our servers.

So who is in charge of this part of the program so I can talk/work with them?

[cfhdev]

While I'm waiting for the contact information I took a look at what I can see about your current setup and see the following.

Currently the SPF record for foldingathome.org is
v=spf1 a include:_spf.google.com ~all

The a in the spf says to use the host in the domains A record but the A record points to 18.224.220.114 and you are sending from 65.254.110.241 (based on the email I had sent to my Gmail address)
You do have a ~all on the end which should generate a SoftFail which should still go through but not always.

At minimum I would suggest you change it to
v=spf1 a ip4:65.254.110.241 include:_spf.google.com ~all

Another method would be to actually use a email user account with credential to send the email. Based on the SPF I would say that it is GMAIL. This way it would come from a google address and be more likely to go through.

We did get an update from the person maintaining the mail server, it might explain part of your issue, some other domains are also having issues getting emails sent. The mail server moved recently, and some of the rDNS settings did not get updated. He was working on getting that done, and getting them propagated out.

Originally the email was being sent from a gmail account, the large numbers of passkey emails sent hit a list set for sending and they stopped actually going out.

[cfhdev]

Any update on this?
I see some changes but still no reply to the two accounts I tried today. (One corporate and on University both using 365).

Here is what Microsoft is asking.
We are looking to see if there is a delivery failure that is being generated on their side. Also if they could provide a message trace showing that it is being rejected by our servers that will help us.
Can you advise which third party application is being used? Is it WordPress? Are they using Contact Form 7?

[Joe_H]

I do know an update to the SPF record was made recently, Wednesday evening. Can you try now and see if an email comes through? If not, I can bring this topic to the attention of the person managing the passkey mailer.

[cfhdev]

Still nothing.

[Joe_H]

Okay, I have sent a note to the person handling the passkey mailer to see if he can take a look.

This is an example of the error I'm seeing many many times in our postfix mail logs:

Has someone requested removal of the block?

[cfhdev]

Thanks for the update. It is being looked into. I will update when I have more info.

[cfhdev]

Response.

Unfortunately I can not tell if someone from the organization has requested the removal of the block, however this is something that they can easily do. For your reference I am providing you an article that will guide you through the process.

[cfhdev]

Has someone with access to that address completed the request yet? and if so can you send me the latest message received.

[cfhdev]

After no update or response from F@H I will close the Microsoft ticket.
