Encrypted email is not being delivered using the Outlook plug-in in test environment. I can see that the email server is not the problem. This is happening to all email addresses, but I am able to check a gmail account, and I don't see it sticking in spam filters, etc. It's not that the email is not encrypted, it just never arrives. Is there a particular format that I should check on the firewall?
