We recommend that you set up your existing SMTP server to send emails from within Workbooks.
If you want to use the Workbooks servers to send your outbound emails then we would suggest yo ...
If you have your own in-house email system, then your IT staff should be able to provide you with the hostname or IP address of your server. If you use a hosted email server, then your service provider can supply you with the details.
Nearly all SMTP servers will block unauthenticated connections; therefore you need to create a user name and password on your email server, so that Workbooks can use the credentials to authenticate.
If you use an in-house server, it is likely that your firewall will block SMTP connections from Workbooks. Therefore your firewall needs to be changed to allow the servers access.
You need to allow access from two IP ranges on port 25.
Range One: 188.8.131.52/28 (i.e. the addresses 184.108.40.206 through 220.127.116.11).
Range Two: 18.104.22.168/28 (i.e. the addresses 22.214.171.124 through 126.96.36.199).
Click Start > Configuration > Email & Integration > Email Settings.
Enter the hostname (or IP address) of your SMTP server in the SMTP Server name field. If you have multiple SMTP servers then you will enter a hostname here which resolves to more than one IP address in DNS.
In the Description field simply add text to document the SMTP server being used.
Select the port number, this is very likely to be port 25, unless your SMTP server has an unusual configuration.
Remember to click Save.
