Configuring an SMTP/POP3 server for faxing Introduction If you are using an SMTP/POP3 server, there are 2 ways of setting up the Email2Fax gateway for these mail servers: 1. Create a routing rule on your mail server which routes all messages sent to the faxmaker.com and smsmaker.com domain to the GFI FAXmaker Fax server machine. You will also need to install and enable the IIS SMTP server on the GFI FAXmaker fax server machine. This is the preferred option but requires that GFI FAXmaker is not installed on the mail server machine itself. 2. Create a dedicated mailbox for GFI FAXmaker on your mail server, which GFI FAXmaker will use to send and receive faxes, e.g. fax@company.com. This option enables you to install GFI FAXmaker on the mail server machine. If Active Directory is being used, you have to ensure that the email address of each GFI FAXmaker user have been entered in Active Directory. If you don’t use Active Directory you have to configure the name and email address of the GFI FAXmaker users. For more information, refer to paragraph ‘Step 3: Specifying the fax administrator & users’ of the chapter ‘Installing GFI FAXmaker ’.
