To know the benefits related to the use of a mail server for sending faxes or receiving notifications by email,
see sections: Using a Mail Server for Sending Faxes on page 36 and Using a Mail Relay Server for Receiving
Notifications on page 36.
A typical fax server/mail server deployment is described in section: Fax/Mail Servers Typical Deployment on
page 37.
Using a Mail Server for Sending Faxes
When a user is sending a fax by email, XMediusFAX finally receives it through its SMTP Gateway
(XMSmtpGateway module), where the email is converted into a fax.
For this, a direct connection is possible between the user and the SMTP Gateway. However, by inserting a
mail server in front of the SMTP Gateway, you can benefit from all special features that such a device can
provide, including:
• A more flexible management and a better performance of email queues (suspend or redirect queues,
manage simultaneous messages...)
• Spam filtering
• Virus checking
Therefore, it is highly recommended to include a mail server to your deployment if you plan to allow users to
send faxes by email. Any mail server can be used for this.
Note: Mail servers like Microsoft Exchange and Lotus Domino can give you access to additional faxing
features, depending on your XMediusFAX license (see Microsoft Outlook Forms on page 41 or Lotus
Notes Form on page 43 for more details).
Using a Mail Relay Server for Receiving Notifications
When a user is expecting to receive email notifications (sending reports or received faxes) from XMediusFAX,
the SMTP Gateway is able to send these emails to any mail relay server (locally or on the Internet). However,
it is highly recommended to insert a corporate mail relay server in front of the SMTP Gateway, in order to
manage locally all the emails sent by the SMTP Gateway before relaying them to the outside. Additionally,
you can benefit from all special features that such a device can provide, allowing:
• To eliminate the effect of communications delays (from the Fax Server perspective) with external servers
(especially through the Internet)
• To receive NDR (Non Delivery Report) messages in case the mail server would not be able to deliver
some notifications sent by the Fax Server
If you plan to allow users to receive email notifications and if you have already a corporate mail system, you
should use it for relaying all emails sent by the SMTP Gateway. Any local mail relay server can be used for
this too.
Note: Mail servers like Microsoft Exchange can give you access to additional notification features,
depending on your XMediusFAX license (see Microsoft Outlook Forms on page 41 for more details).
