There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<server.domain.local #5.5.0 smtp;550 XXX.XXX.XXX.50 blocked by ldap
u=rblmx,dc=comcast,dc=net -> BL003 Blocked for spam. Please see
I called comcast and they said that our IP is not on the block list althought it was at one point. Is there any way to determine what RBL has us in their list of unwanted IPs?
