It's got nothing to do with MX; it's a bug on the RaQ3; see my previous
post on this thread.

Yes, each domain must have it's own MX record.  If you're doing DNS for
your domains, then you need it.

It can be something as simple as the line:

domain.com.  IN MX 10 domain.com.

in the zone file for domain.com.

They all do use the same physical mail server, presuming they're hosted
on the same RaQ; you only have one sendmail installed.

You can address it any way you want, but you're responsible for the
address.

You can certainly use:

customersdomain.com.  IN MX 10 mail.mydomain.com.

as long as you have an record for mail.mydomain.com.

The "system" does no such thing.  It's your job.
