All incoming emails are rejected with this message: Remote host said: 554 5.7.1 Service unavailable; Client host [87.248.110.143] blocked using rabl.nuclearelephant.com [RCPT_TO] I need to bypass / update or kill the service (I think it should be a spamassassin list problem). Please help.
spamassassin is not rejection emails like this with a 554 as it scans emails after they are fully received. Most likely you specified this blacklist in postfix main.cf, so you should remove it there.
I had all my emails being rejected by this service yesterday as well and had to comment out it's use. Anyone know what happened with this service?
