MX records query

Hi,
I have two quick questions regarding MX records. Could you please help me:
1) Do I change my MX records at my domain name provider or my hosting provider?
2) My email provider (different from domain provider as well as hosting provider) has given me only one MX record with priority 10. Does this mean that there will be no MX record with priority 0? I know they should be the ones answering this, but they always seem to answer a question different than the one I ask
Thanks for your help

1) I think you need to do this with your hosting provider
2) With the priority it is just the lowest number that is tried first, not sure why they choose to use 10 so often (all my backups seem to be 20) but that should be fine, I'm not sure if 0 is even allowed

I find providors are notorious for answering different questions to those asked.

I think the answers I've provided are correct but I've only just mastered my A,B,C's and am a big time novice with the MX subject

 

You change them at the place that is hosting your nameservers. This could
be either one depending on how you set things up. Most seem to use their hosts these days.

It means that yes, with only one MX record that is the one used, so priority is a non issue.

 

Thanks dct, jbw.
