I've seen some mailservers refuse a connection when > the person sending doesn't have matching forward and reverse DNS > (eg freebsd.org :) well that depends if its the machine or the MX record :) The machine which handles mail for the domain I mentioned is 'tigger.key.co.za' and it has correct forward and reverse lookups: tigger.key.co.za <-> 196.2.147.10 But the MX record for key.co.za is 'mx.key.co.za' however. This resolves to the same IP. I'll try change the MX hostname and see if this resolves things. Would still be interesting to hear if anyone knows this to be an RFC requirement.
