Milter-greylist

Comcast is probably using many different mail servers to resend messages 
so my question is have you configured subnetmatch?

 From man page:

/subnetmatch/
    This is equivalent to the *-L* command line option. It takes a slash
    followed by a CIDR mask as argument, and it commands the subnet
    matching feature. Example, for a class C wide matching:
subnetmatch /24
/subnetmatch6/
    This is equivalent to the *-M* command line option. It takes a slash
    followed by a prefixlen as argument, and it commands the subnet
    matching feature. Example, for a subnet wide matching:
subnetmatch6 /64
