Remarks

If the e-mail client does not match the network requirements, it should try other protocol types. ISPs may provide one set of servers with Protocol tags that do not require authentication but are required to be on the ISP network. ISPs may list another set of servers that require authentication but are not required to be on a specific network.

The NetworkRequirements element is optional.
