I have an issue with mail getting rejected from a specific
domain. It's getting rejected due to Spamdyke and RDNS. Here's the
line out of the log.
Jul 16 09:02:41 vm1 spamdyke[32358]: DENIED_RDNS_RESOLVE from: ***@**nd.com to: ***@**ion.com origin_ip: 50.**.**.98 origin_rdns: 50-**-**-98-static.**.comcastbusiness.net auth: (unknown) encryption: (none) reason: (empty)
From looking at the log. It says spamdyke is blocking it due to RNDS not resolving. But then on the same line it shows the "origin_rdns" and it looks like a valid reverse dns to me.
Why is this getting blocked?
