We are using constant contact tool to communicate few messages internally. Our security team has put a rule that checks if the email domain is other than corporate domain then mark them as SPAM.
We want to whitelist only emails getting generated from Constant contact domain those are specific to our company. I tried to review the email header but was not able to find field that will help me to identify our company.
Has anybody come across this situation or does anybody know any field that I can use to make determination?
Thanks in advance.
I sent you an email too, but just in case others people have this same question. You can have your IT Whitelist Constant Contact Email domains in general and this will allow our emails to come through. Here are the articles with that information:
