@tychotithonus @Jerry It will probably work OK with 10 - that's supposed to be a relative number, for when there's more than one MX record and a "main MX / backup MX" disposition is desired. As with line numbers in BASIC, the default is 10 to allow for numbers to be added above and below. The important part is the null host (single dot). But I wouldn't want to rely on every other mail server interpreting that correctly.
