In my maillog I get messages like this. The user/domain/ip have been changed, but they are all valid:
spamdyke[10162]: DENIED_RDNS_RESOLVE from: [email protected] to: [email protected] origin_ip: 162.xxx.sss.yyy origin_rdns: server.domain.com auth: (unknown) encryption: TLS reason: (empty)
These messages get rejected by my server. My understanding is the messages are getting rejected by spamdyke due to un-resolvable reverse dns (DENIED_RDNS_RESOLVE).
However, further down in the same log message it lists
"origin_rdns: server.domain.com" which IS the valid
reverse dns of the domain that sent the message.
So how can it be rejected by reverse DNS but then show the proper reverse DNS?? What am I missing here?
Thanks, GB
