To work with the anti-spam service it is necessary to enter a record in the DNS zone of the protected domain(s):
| Name | Type | Value | Weight |
| @ | MX | antispam.cloud4u.com | 10 |
All other MX records must be deleted (except for special cases where the letters are pre-processed before filtering).
Please note
To resolve the issue of delivering spam-screened emails, you will need to add the IP address of SpamTitan to the transport configuration of your Mailbox/Edge Exchange Server. You can use the following command to do this:
Set-TransportConfig -InternalSMTPServers @{ Add = "176.53.181.180","176.53.183.133"}
SpamTitan server IP address: 176.53.181.180
This is due to the fact that SpamTitan is an SMTP relay and when performing filtering, it substitutes the sender's address for its own, so it fails the SPF check.
In case you use Saas Exchange and SpamTitan services, you need to change the SPF record values in your domain DNS records.
