There are rDNS for IPs between 204.15.82.20 and 204.15.82.25, but I'm still unable to register my mailhost:
Connecting to mx1.xxxxxxx.org.:
smtpSend:smtpEnvelope (service[at]admin.spamcop.net, thierry[at]xxxxxxx.org): smtpTo rcpt to:thierry[at]xxxxxxx.org (450 : Helo command rejected: Host not found )
Does spamcop send test mails from other IPs, or is there any other possible reason?
(I have tried a lot of times, and of course my mailhost is up and running).
