1 Email Environment

1.1 No in-house Email Server, the end-user getting emails from external service provider

1.1.1 Using Europa as the internal email server and a SPAM filter

See Enable the email server for a domain (below)

The end-user continues to pull down the emails from external service provider.

  • From Europa user's Quarantine Manager page > Email Admin > MPOP Setup > Fill-in MPOP account information.

User then changes email program's both incoming/outgoing fields from the service provider to Europa.

  • Example: Outlook Express > Internet Mail Account > Properties > Servers > Change the Incoming/Outgoing mail fields to Europa IP address.

Note: If your internet service provider (such as Rogers/Bell Home Internet service) blocking all the outgoing SMTP port traffic, the end-user should not change the outgoing mail field to Europa.

1.1.2 Using Europa as the external Email Server and a SPAM filter

See Setup Europa as an external Email Server (below). The rest is same as above.

1.2 Has an in-house Email Server, already receiving emails from external MTA

Please verify the setup with Setup Europa as an external Email Server (below) and Enable the email server for a domain (below).

1.2.1 Email Server only

  • Europa System - Service Info > Domain Service Setup > select a domain
    • Select No in Enable Email Service
    • Change the email deliver to address by filling in Email Server IP address.
  • On firewall, change the SMTP port (25) forwarding address from the existing email server to Europa IP address.

1.2.2 Email Server build-in SPAM filter software

Same setup as above and you should consider to disable or to uninstall this software since

  • Europa already protecting your email server from IP connection and SMTP email levels.
  • Europa aleady filter out SPAM, virus, and perform Black/White listing for the user.
  • In general, this type of software consuming system resources and slow down your email server.

1.2.3 Another email filter appliance and Email Server

In general, you can disconnect this email filter appliance and replaced it by Europa. Just in case, you want to serialize Europa with this appliance:

1.2.3.1 Put Europa in between this appliance and email server
  • Europa System - System setup
    • Select Yes in Behind Mail Gateway and fill-in Mail Gateway IP address.
  • Europa System - Service Info > Domain Service Setup > select a domain
    • Select No in Enable Email Service and fill-in Email Server IP address.
  • Logon to that appliance, change the delivery IP address from email server to Europa.
1.2.3.2 Put Europa in front and deliver email to that appliance

This means Europa will deliver email(s) to that appliance instead of to a real email server

  • Europa System - Service Info > Domain Service Setup > select a domain
    • Select No in Enable Email Service and fill-in that appliance IP address in Email Server field.

1.3 Using External Email Filtering Service

See Has an in-house Email Server, already receiving emails from external MTA (above) to configurate your Europa. Once Europa is protecting your email server, you can consider:

  • Redirect the email traffic to your IP address by changing your MX record to your IP address.
    • Note: The DNS reverse lookup PTR record is highly recommended, you should change the MX and the PTR records at once.
    • See the How can I verify my DNS, MX, PTR, Mail records? section (below).
  • Once you can directly receiving email from other MTA, you can cancel that external email filtering service.

  • Enable the email server for a domain (below)
  • Add or change the SMTP port forwarding rule into the firewall: from external port 25 to internal Europa IP port 25.
