Odds are they're blocking you for having a PTR record containing ".dsl."

#host 69.17.96.163
163.96.17.69.in-addr.arpa domain name pointer dsl017-096-163.lax1.dsl.speakeasy.net.

If this really is a static-ip'ed mailserver, talk to speakeasy about getting
your PTR records set to match your DNS name of hoshi.pixelmagicfx.com.
