ReplyToChatter and EmailToGroup email security protocol checks
|Knowledge Article Number||000240599|
|Description||When a user sends a ReplyToChatter or EmailToGroup email, sometimes the email is not processed and does not show up in Salesforce. This could be due to security protocol check failure.
|Resolution||For security purpose, the above features use enhanced mail authentication for the incoming emails and only allows e-mails that can verify the sender via:
a. The domain owner’s Sender Policy Framework (SPF), or
b. SenderID, or
Salesforce requires that neither SPF nor DomainKeys fail. Neutral/missing is fine.
Salesforce requires each e-mail passes at least one of the security protocols above and that it does not fail any.
