one of my users gets blocked by spamhaus on domain2.com:
May 4 12:04:47 mail postfix/smtpd: NOQUEUE: reject: RCPT from xxx.xxx.xxxxxxx.xxx[xx.xx.xx.xx]: 554 5.7.1 Service unavailable; Client host [xx.xx.xx.xx] blocked using zen.spamhaus.org; spamhaus.org/query/ip/xx.xxx.xx.xx; from=<domain2.com> to=<domain2.com> proto=ESMTP helo=
How ever, the user has a mailbox on domain1.com and this works fine for weeks.
Spmhaus tells me on their page:
Outbound Email Policy of Time Warner Cable/Road Runner for this IP range:
It is the policy of Time Warner Cable/Road Runner to share with other entities lists of our dynamic IP address space. While Time Warner Cable/Road Runner does not currently forbid customers from sending out mail directly from such space, it recognizes that others may wish to refuse mail from such space, and so Time Warner Cable/Road Runner makes that space known to others to facilitate their enforcement of their policies. Customers finding their mail refused by others due to a PBL listing should send their outbound mail through the outbound mail server designated for them; see http://help.rr.com/HMSFaqs/e_emailserveraddys.aspx for more information on the servers’ names.
Removal of IP addresses within this range from the PBL is not allowed by the netblock owner’s policy.
any ideas what i can look at?
