SPAMCOP.NET was not renewed as a domain by CISCO. There’s a big write up on Reddit.
https://www.reddit.com/r/sysadmin/comments/l9asw7/spamcop_domain_expiredparked/ and https://www.bleepingcomputer.com/news/security/spamcop-anti-spam-service-suffers-an-outage-after-its-domain-expired/ So, you could say “This outage brought to you by, CISCO…” … Carl From: Jaime Lerner [mailto:jaimeler...@geekgoddess.com] Sent: Sunday, January 31, 2021 06:13 PM To: qmailtoaster-list@qmailtoaster.com Subject: [qmailtoaster] Spamcop's RBL went rogue today for me Just an FYI that from 11am ET this morning EVERY single email that was delivered to my server got rejected from Spamdyke as "DENIED_RBL_MATCH" because I had bl.spamcop.net listed as one of my "dns-blacklist-entry" settings (along with spamhaus and barracudacentral). I was finally notified via text from one of my clients that their email to be bounced as undeliverable so I checked the server at 5pm and found all the rejections in the maillog file. Yikes! In case someone else has bl.spamcop.net in their spamdyke.conf file you may want to check and make sure that server is receiving mail OK. Have no clue what caused it.
