How to define outbound email separator in EngageOne Digital Delivery

Product Feature: Administration
The documentation says the following:

For providing email id delimiter for configured mail server to support multiple recipients of email. The separator should contain "@" between two delimiters. e.g.,@;

You would only use this option if the email server supported multiple email address separators, ie both comma and semi-colon.

If the email server only supports a comma, you would define this as a comma, if it only support a semi-colon as the separator, you would define this as a semi-colon.

If you require any further clarification please contact Technical Support.
