To ensure that RedTeam can send emails on behalf of a user's email account without them being marked as spoofed or spam, the SPF (Sender Policy Framework) record needs to be updated. This update authorizes RedTeam to send emails on behalf of the user's domain.
Please ask your IT Department to add RedTeam to the allow/whitelist on your mail
server and/or DNS SPF records.
Create an SPF record for your domain
1. Log in to the administrative console for your domain
2. Locate the page where you can update the DNS records
3. Create a TXT record containing the below text. (If a txt record already exists, please append to your existing record to keep the mail flow functioning.)
If you use Outlook/Microsoft 365:
"v=spf1 a mx ip4:168.245.113.179 ip4:168.245.125.157
include:spf.protection.outlook.com include:sendgrid.net ~all"
If you don't use Outlook/Microsoft 365:
“v=spf1 a mx ip4:168.245.113.179 ip4:168.245.125.157 include:sendgrid.net
~all”
Note:
Publishing an SPF record that uses -all instead of ~all may result in delivery problems. Please verify with your IT Department or Email Service
provider for the correct info.
To authorize an additional mail server:
add the server's IP address just before the ~all argument using the format ip4:address or ip6:address. (See Sender Policy Framework for more details on the SPF format.)
4. Save your changes. Your new SPF record can take up to 48 hours to go into effect, but this usually happens more quickly.
Avoid adding multiple SPF records
Adding more than one SPF record for a domain can cause problems with mail
delivery and spam classification. Instead, we recommend using only one SPF
record. For more details about Multiple SPF records, click HERE

Note:
Any changes made incorrectly will break the mail flow to the user’s
account. Please make sure to verify with your IT Department or Email Service
Provider the correct SPF record settings and update procedures before
making changes.
