Unforgiven23 Posted December 5, 2006 Share Posted December 5, 2006 First time poster here needing help with something strange going on with my mailserver. For about a 2 year period now I've been using bl.spamcop.net and sbl-xbl.spamhaus.org as dual RBL options for my company mailserver. I have had issues with Spamhaus going down from time to time and outside emails being rejected with SMTP errors. Disabling sbl-xbl.spamhaus.org let email through and I re-enabled it a few days later without issues after talking with their tech support and them stating they were having server issues. For the last 12 hours I have had to disable bl.spamcop.net because outside emails were being rejected. Here is the error message being sent back to outside sources: This is an automatically generated Delivery Status Notification Delivery to the following recipient failed permanently: xxxxx[at]domain.com Technical details of permanent failure: PERM_FAILURE: SMTP Error (state 9): 550 Requested action not taken. Is anyone else experiencing the same issues over the past 12 hours with bl.spamcop.net as a RBL? No configuration changes have been made to the server in that time. I have since restarted multiple times but anytime I enable bl.spamcop.net emails immediately start being rejected. The rejections are from multiple domains so I know it's not just a single domain that has accidentally been blacklisted. Any help is greatly appreciated! Thank You!
