As of this morning most external emails are getting bounced back to sender because the RBL feature seems to be broke. At first it was saying addresses where listed list.rdbl.org and then when I disabled that RBL, it took the next one in my list(spamhaus).
I just opened a case with support. Currently I have the "Use RBLS" disabled to get email into us. We have been running fine on 6.303 since I updated(13 days ago).
Any ideas? I guess I'll start going through logs.
