Kudos to Gareth T. who pointed out that I forgot to update my SPF record, which includes a "-all". I've updated my SPF record and will try again after my old info expires out of caches. -- Grant. . . . unix || die On 07/23/2015 02:42 PM, Grant Taylor via NANOG wrote:
Hi,
I was wondering if there were any GMail contacts on NANOG that might contact me either on or off list for some help.
I am having problems sending email to GMail from my new (< 2 weeks old) Linode VPS.
tncsrv06.tnetconsulting.net (IPv4: 45.33.28.24, IPv6: 2600:3c00:f03c:91ff:fe26:8849)
I have forward and reverse DNS set up as well as following all of the same practices that I have used to administer email servers for the past 15 years. So, I think that I have everything covered. (If I've missed something, let me know and I'll take care of it.)
Is there a chance that my IP address(es) (v4 and / or v6) have been blocked because of previous IP user actions? Or am I by chance part of a netblock that is black listed?
Below is the multi-line SMTP response that is showing up in the DSN that I'm receiving.
<<< 550-5.7.1 [2600:3c00::f03c:91ff:fe26:8849 12] Our system has detected that <<< 550-5.7.1 this message is likely unsolicited mail.

Any help or suggestions you could provide would be greatly appreciated. I'm in the process of migrating off of my old server to my new Linode VPS as part of a move and would like to get this quickly, if possible.
As a temporary work around, I have routed gmail.com email to my other Linode which can send email to GMail.

Thanks for your time and any help you can provide.
