specific emails i dont receive

Question

I am not receiving emails from psychoanalysis.org.il (specifically - ******@psychoanalysis.org.il). The message's domain is - newmass.impactia.com

I have checked my junk folder and safe senders list. Could you please check if emails from this domain are being blocked or filtered?

Thank you.

Answer 1

If you are not receiving messages from a specific sender or domain, the issue is usually caused by one of the following areas: sender side delivery failure, Microsoft 365 filtering, transport rules, or mailbox level rules.

Please go through the checks below in a structured way.

First, confirm whether the message is reaching your tenant.

If you are an end user in a Microsoft 365 organisation, ask your administrator to run a Message Trace in the Exchange admin centre.

1. Go to Exchange admin centre.
2. Navigate to Mail flow, then Message trace.
3. Search using the sender address or domain newmass.impactia.com.
4. Check the status of the messages.

If the message does not appear in the trace results, it means the sending server is not successfully delivering to your tenant. In that case, the sender must check their outbound logs, SPF, DKIM, and DMARC configuration.

If the message appears but shows as Failed, Blocked, or Quarantined, review the reason code.

Second, check quarantine.

1. Go to Microsoft 365 Defender portal.
2. Navigate to Email and collaboration, then Review, then Quarantine.
3. Filter by sender domain or recipient.
4. If messages are present, review the threat reason and release if appropriate.

If the messages are classified as High confidence spam or Phish, this indicates an authentication or reputation issue on the sender domain.

Third, review anti spam and anti phishing policies.

In Microsoft 365 Defender:

1. Go to Email and collaboration, then Policies and rules, then Threat policies.
2. Review Anti spam inbound policy.
3. Check whether the sender domain is explicitly blocked.
4. Check Tenant Allow Block List for any entries related to psychoanalysis.org.il or newmass.impactia.com.

Fourth, check mailbox level rules.

In Outlook or Outlook on the web:

1. Open Settings, then Mail, then Rules.
2. Confirm that no rule is automatically deleting or moving messages from that domain.
3. Also check the Blocked senders list under Junk email settings.

Fifth, verify authentication alignment.

If the sending domain is psychoanalysis.org.il but the actual sending domain is newmass.impactia.com, Microsoft 365 may treat this as spoofing if SPF, DKIM, or DMARC are not correctly aligned. The sending organisation must ensure:

SPF includes the sending infrastructure. DKIM is enabled and valid. DMARC policy is correctly configured and aligned with the visible From domain.

If you are not the tenant administrator, you cannot directly check filtering decisions. You must involve your Microsoft 365 administrator to perform message trace and policy review.

Most cases involving specific domains are caused by sender side authentication misconfiguration or tenant allow block list entries. A message trace result will clearly identify which of these applies in your case.
