Prevent spoofing.
I do have a smtp proxy setup with prevent spoofing in it enabled. Mentime secure email is being used and all secure emails from/to internal users are being blocked. Is any way to add exceptions on prevent spoofing for specific domain or something....
here are the logs:

What exactly are your Prevent Spoofing settings?
Mail from rule: rule settings - pattern match : *@domain.org Action : drop
Header Rule: rule settings - pattern match : *@domain.org * Action : drop
I think i did follow WG resources for it.
From: =
[email protected] via SecureMail" [email protected]
So you need a rule above Mail from and header rule allowing @domain.org via SecureMail
