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.

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. tncsrv05.tnetconsulting.net (IPv4: 109.74.192.125, IPv6: 2a01:7e00::f03c:91ff:fe89:2935) Thanks for your time and any help you can provide. -- Grant. . . . unix || die P.S. I did send an email to postmaster@gmail.com, but it bounced saying that the address had been disabled.

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 Christopher, Unless my eyes are deceiving me, I think "host" ate a colon in "::" for you. I *think* that I have forward and reverse DNS set up properly for both IPv4 and IPv6.

Thanks for the second set of eyes, because I obviously missed something. -- Grant. . . . unix || die On 07/23/2015 03:03 PM, Christopher Morrow wrote:

you probably also want to fix that...
After updating my SPF record per Gareth's recommendation, email now seems to be flowing to GMail properly. -- Grant. . . . unix || |die On 07/23/2015 02:54 PM, Grant Taylor via NANOG wrote:

May not be the case here, but I had an issue with my Linode and IPv6 email (not with gmail.com though). If you just "request IPv6", you get a single /128 out of a common /64. The problem is that most people doing IPv6 anti-spam treat reputation on at least the /64, not individual /128s. You can request a /64 from Linode, no additional charge. I switched to using my own /64, and I haven't had any issues since. I use Lynx to look things up in Google sometimes, and was also periodically getting blocked from that (with a captcha!). Since switching to my own /64, I haven't had any issue there either. -- Chris Adams <cma@cmadams.net>
