Testing your connection
Getting Started Guide | Forcepoint Email Security Cloud
When you add a domain, Forcepoint Email Security Cloud checks for a valid inbound connection for this domain and displays the result on the Add Domain screen, accessed through the Domain tab. If it cannot find or validate a connection, an error message appears. The inbound connection checking does not guarantee the correct delivery of email messages. It is strongly recommended that you run your own testing on the inbound connection that you have specified.
We also recommend that you test your outbound connection before configuring your policies and beginning mail flow.
To test your outbound connection with the Forcepoint Email Security Cloud service, you can open a telnet session to the service IPs on port 25 using the DNS names you've been assigned, then simulate sending a message:
1.
a.
Select Start > Run
b.
c.
Press Enter.
2.
telnet custXXXX-1.out.mailcontrol.com 25
 
replacing custXXXX-1.out.mailcontrol.com with the first customer-specific DNS record on the Service IP Addresses page in the cloud portal. You should receive a response like this:
 
220 cluster-[x].mailcontrol.com ESMTP MailControl
 
3.
helo [your server name]
 
For example:
 
HELO mail.customerdomain.com
 
Response:
250 cluster-g.mailcontrol.com Hello mail.customerdomain.com [192.168.1.1], pleased to meet you
 
4.
mail from: postmaster@yourdomain.com
 
For example
 
mail from: postmaster@customerdomain.com
 
Response:
250 2.1.0 <postmaster@customerdomain.com>... Sender ok
 
5.
rcpt to: Your Web mail address
 
Response:
250 2.1.5 <yourname@yourcompany.com>... Recipient ok
6.

9.
telnet custXXXX-2.out.mailcontrol.com 25

rcpt to: Your Web email address

quit
10.
telnet custXXXX-s.out.mailcontrol.com 25

Any of these records can be used to route your email.
If you receive a "relaying denied" error, 1 of 2 things could be happening:
*

When you successfully connect to the service, you are ready to change the configuration of your Internet mail gateway.
Once you have changed your Internet mail gateway configuration, you can test the delivery of outbound email via Forcepoint Email Security Cloud by sending to an echo address. For example:
echo@uk.psi.net
If your email does not get through, check its progress using Message Center in the cloud portal, or contact the Forcepoint Support helpdesk.
