I had the following error:
<[email protected]>: host yyyyyyyyyyyy.yyyyyyyyyyyyy.de[33.33.33.33] refused to
talk to me: yyyyyyyyyyyy.yyyyyyyyyyyyy.de (mxeue106) Nemesis ESMTP Service not
available 554-No SMTP service 554 invalid DNS PTR resource record
Evidently I need to set the PTR records, in this forum thread invalid DNS PTR record.... I see that :
whilst the IP is backwards, the numbers themselves are not
So if i have an IP
like 22.33.44.55
I supposedly need to have this add:
55.44.33.22.in-addr.arpa 300 IN PTR www.dummy_domain.com
Is .in-addr.arpa
suffix mandatory?
Also I have IPs that are not managed by the my DNS provider can I add those too to my IP?
Thanks
Note: IP and names here are not reflecting reality, 22.33.44.55
and www.dummy_domain.com
are not mine and [email protected]
, yyyyyyyyyyyy.yyyyyyyyyyyyy.de
, 33.33.33.33
are changed
