The MX records is malformed. The safe thing to do is to not accept garbage.

Errors should not be ignored, the malformed "cluster8a" MX host must
not be used.

Postfix 2.5.7 will likely be able to connect to the "cluster8" MX host.

The unreleased "smtp-finger" code is essentially identical to the code
in the SMTP delivery agent, both call smtp_domain_addr() to resolve
the MX host list. So if smtp-finger can connect, I'd expect the same
from smtp(8).
Feel free to try 2.5.7. If you want more help, you really should report
full log entries from a failed delivery (all loging from the smtp(8)
delivery agent with the same process id that reports the final delivery
error, preceding that error, but not associated with a previous transaction).
