Purpose:

The purpose of this document is to describe the whitelisting requirements for SMTP E-Mail services.

DNS Domain Modification:

When an E-mail message is sent by a domain where the sender is different than the SMTP server’s domain, it will report out as a softfail through MIME headers. Some clients prevent E-mails which report a softfail from coming through their SMTP server. To validate the client’s domain as a valid sender for our SMTP servers, thus preventing a softfail, the following DNS modifications are needed:

1.      Update domain’s root TXT SPF record by adding: include:_spf.mitracloud.com

Firewall Filter Rule: 

Blocked Notifications

There are features in TeamConnect which send notification emails on behalf of a user to other users.  For example, User A assigns User B to a matter: TeamConnect will send a notification of that assignment using "usera@company.com" as the sender email address.  Many corporate firewalls will flag these emails as using a spoofed email address and will block them.  In order to allow these emails to reach their intended recipients, you may need to whitelist the IP addresses of Mitratech mail servers.  

Following are the IP addresses that need to be whitelisted. A new tcp protocol rule for the following addresses may be required:
