I hope you don't mean that the name "mail.server2.net" now points to
200.200.200.101.  Only the MX records for server2.net need to point to
the first host, so that mail for the domain is delivered to this host.

IIRC, this isn't right.  You should only list mail.server2.net in the
local-host-names of 200.200.200.102.

This seems ok.

This seems ok too.

That's because mail.server2.net points to the address 200.200.200.101.
When sendmail on that host tries to deliver the message as per the
instructions of your mailertable, it discovers that the message is sent
back to itself!  A loop...
