Benefits of filtering outbound emails through Xeams

Xeams is capable of filtering inbound as well as outbound emails for your company. Filtering outbound email is as important as filtering inbound messages therefore, it is strongly recommended you configure your primary email server to send messages through Xeams when sending messages to users on the Internet.


This page assumes you are using Xeams in Firewall or Hybrid mode.


  • Auto Learning - Inbound email filtering improves when you send outbound emails. For example, inbound messages from a friend or business colleague receives credit when Xeams has previously encountered outbound emails.
  • Message Archiving - Since every message is saved and indexed in Xeams, it is very easy to find an older message by searching it by content or sender/recipient email address
  • Security Alerts - Xeams will generate security alerts to the administrator if it detects unusually activity or a high volume of message being sent out
  • Outbound Diagnostics - Xeams contains outbound diagnostic tests that can notify administrators if one or more configuration is incorrect, allowing them to pro-actively fix problems on their network
  • Deliver Status - It is very easy to check if Xeams was able to deliver the outbound email to the next SMTP server. This can be done by looking at the status icons, or referring to log files such OutboundAuditTrailSuccess.log and OutboundAuditTrailFailure.log

Preparing Xeams for Outbound Emails

Assume you are using Microsoft Exchange as your primary email server, which is running on You will have to add Exchange's IP address in following locations in Xeams.
  1. Whitelisted IP - Go to Whitelisted IP Addresses under Filter Management and add your Exchange Server's IP address
  2. Trusted IP - Go to Auto-Learn Sender Filter under Filter Management/Adaptive Filters, click the button for Manage Trusted IP Addresses and add Exchange's IP address
  3. Relaying - Go to SMTP Configuration under Server Configuration and click Relaying. Add Exchange's IP among the Relaying list.

Configuring your actual email server

Finally, you have to configure your actual email server to send messages through Xeams. Although every SMTP server is different and it is impossible to give instructions for each individual server on this page, this feature is typically referred to as Smart Host or Relay Server in many systems. For example, in Exchange you have to configure the Send Connector to use a Smart Host by specifying Xeams' IP address.
