Much of the budget hosting these days provides reasonable web storage 
and generous web traffic limits, but most seem to offer a single MX 
record.   I'm looking for web hosting: single domain, multi-domain, 
and reseller levels, which aren't hundreds of pounds/dollars a year 
(though that's quite possible, or even likely, for UK-based hosting) 
where my major requirement is to have two or more MX records.   

It's not really a luxury, indeed there's probably some RFC which 
says it is desirable, but does seem to be missing with most that
I've seen over the last year or more.  Sure I'm not blind, but 
if someone has seen this mentioned on any web-based hosting 
comparisons, a link to same would be welcome.

Otherwise, posts (from customers and hosting firms) would be welcome 
(but if a hosting service, please make that clear so you don't get
complaints of putting forward your service and not declaring an 
interest).  

Thanks in advance, guys.
