As the listadmin, I'd like to apologize for some recent lists mail loss.
A spammer managed to get a subscription confirmation email send to a
spamtrap address, that promptly caused the lists server to be listed on
a blacklist for 12-14 hours.
During that time, approximately 2000 list deliveries were rejected due
to the RBL. First recorded rejection was around Feb 1 00:20 UTC, last
recorded was Feb 1 13:35 UTC.
I've included full log details in a blogpost:
If you know anybody that runs similar spamtraps, please ask them to
ensure list confirmation requests are NOT treated as spam.
