Very strange, but the past week or so myself and customers have started to have loads of emails go into to spam.
Gmail’s IP has recently gone into sorbs so no Gmail was accepted. I reduced the score.
But ALL of my server incoming emails have a score for dnsrbl.org all of a sudden. My server has worked for years, then all of a sudden we have a score for this DB even though when I check the IP it is not listed on dnsrbl.org.
4.0 RCVD_IN_RBL_DNS RBL: Entries listed in dnsrbl.org RBL
I have had to change the dnsrbl.org score to 0.
Anyone have any idea why this may be, could it be a server issue, or could it be an issue at dnsrbl.org returning a false positive?
