Email Routing
Use this information to plan and set up the email routing for using GFI MailSecurity.
Inbound Mail Routing Requirements
Configure your email domain's MX records to point to GFI MailSecurity. This enables all inbound emailEmail to be received. to get filtered by the Security service.
To do this, replace your current MX records with the following records:
| MX Record | MX Preference |
|---|---|
| EU DataCenter | |
|
eu01.gfimailsecurity.com |
5 |
|
eu02.gfimailsecurity.com |
10 |
| US DataCenter | |
| us01.gfimailsecurity.com | 5 |
| us02.gfimailsecurity.com | 10 |
| us03.gfimailsecurity.com | 15 |
This ensures that all inbound emails get routed and processed by GFI MailSecurity before reaching your infrastructure.
NOTE
Secondary or other MX records are not usually required. Be aware that spammers sometimes target secondary or lower priority MX records which may not be protected by spam/virus filtering.
Ensure that your mail server accepts inbound messages from the GFI MailSecurity Data CenterA remote location on a GFI MailSecurity Server through which the email traffic is santized and then routed to the Exchange Server. It is also used for queuing emails during outage and for storing archives and synchronized calender and contact information.. If your gateway server blocks inbound messages that use your domains in the From: field. Add an exception to this rule to accept messages originating from GFI MailSecurity.
For example, if your domain is mydomain.com and you block all inbound mail with an SMTPSimple Mail Transfer Protocol (SMTP) is an Internet standard used by GFI OneGuard for electronic mail (email) transmission. SMTP by default uses TCP port 25. address of *@mydomain.com as spam, modify this policy to exclude the GFI MailSecurity Data Center.
Firewall configuration
Configure your firewall to accept inbound SMTP traffic (port 25) from GFI MailSecurity. Also, configure GFI MailSecurity IP addresses to be a trusted forwarder, but not safe-listed.
