That could be the problem, if certain misconfigured senders 
consistently produce the problem (as there is no requirement that a 
domain have an A record to exchange mail, and FcRDNS works for the 
given domain).  OTOH, if the problem is transient, then it may reflect 
an issue with DNS propagation or the DNS servers, an issue I 
occasionally see.  The OP wasn't clear on this.
