about MX hosts

Wesley Peng-6
Hello

I saw my ESP has two MX records pointing to just the same host.

rambler.ru.             21      IN      MX      5 inmx.rambler.ru.
rambler.ru.             21      IN      MX      10 inmx.rambler.ru.

Does this have any value inprovement?

Thanks

Unlikely, but perhaps some DNS provider *requires* two records,
and this is how they work around it.
