Why?

Quite often IPs without reverse DNS are used by spammers

Remailers don't read their mail. Unless the spam is encrypted into a valid
mix packet, nothing happens. So why block out legit users without reverse
dns?

Quite often remailers have no reverse dns as well. Mostly due to them not
having any control over the reverse zone for the IP their ISP gives them.
Somehow I do not think that remailers are going to call up their ISP's and
ask them to set reverse dns for the remailer on one of their IP's.  I would
be nice if pobox.antagonism.org lifted this rDNS requirement. Stats are not
maitained on what remailers do have a rDNS so *not knowing* may break some
chains.

I actually did not know the OP was talking about a remailer and I though
that he referred to pobox.com
