Create an Email Alias and Set Up Forwarding
NetSuite generates an email address for use with the plug-in implementation. Users can send email messages to the implementation’s email address for processing. However, you may want to create an email alias on your company mail server to mask the email address required by the plug-in implementation.
For example, if your account ID was 123456, the NetSuite-generated email address for a plug-in implementation look something like emails.123456.xxx.xxx@1234567.email.netsuite.com and the implementation processes email messages to create Invoice records in NetSuite. You can create an email alias named invoices@example.com on your company mail server that forwards to the implementation email address.
You can then release invoices@example.com as the email address for your customers to use when sending invoices.
