Though it is desirable to have a valid MX record, it is not essential 
according to RFCs.

There appears to be a valid A record, this should be sufficient - only a 
brain-dead admin would configure his MTA to require MX records.

PTR records match A records (not MX records).  Again, according to RFCs, 
SMTP servers are not supposed to reject mail due to the absence of PTR 
records and/or PTR not matching A;  but, many admins configure things 
that way in an attempt to reduce spam - this is neither, very effective 
(IMO) nor, a good idea.
