Backup MXes

I thought people might be interested, in particular, in my post's second
half's comments about backup MXes, and disadvantages thereof.  The
reason this is connected to dnsreport.com's CGI is that it (currently)
advises those (like me) having only a single MX that "there is a chance
that mail may have troubles reaching you", implying that this is an
undesirable and dangerous MTA configuration.

That advice is given frequently enough that I thought my reasons for 
profoundly disagreeing would be of interest.

If I erred, then my apologies for the intrusion.
