I can sending out email now but all into spam.

I am actually confused of https://github.com/atech/postal/wiki/Domains-&-DNS-Configuration this article instruction.

I have copy all DNS record from my server domain config page likes below, but still unable pass the test of postal "check my records are correct", would Adam able to explain to me more about it.

I have use godaddy for DNS setup with just one single ip.

SPF Record

WARNING No SPF record exists for this domain

You need to add a TXT record at the apex/root of your domain (@) with the following content. If you already send mail from another service, you may just need to add include:spf.postal.example.com to your existing record.

v=spf1 a mx include:spf.postal.example.com ~all
DKIM Record

WARNING No TXT records were returned for postal-QZwUIn._domainkey.mx.amotic.net

You need to add a new TXT record with the name postal-QZwUIn._domainkey with the following content.

v=DKIM1; t=s; h=sha256; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDD99mJOLwgfWOjt17QobkLEyeVGSLqB/okptFQ+/muisbU7wddvP3F3ii6CfbMZvVz+YdirHnVpTyBPaAv/7kn6soqBX1zakkBl4VlqZ9bsFohoTKjZwGWJOhytoz7c1RVZD0H3PvyCt6/pYbiTg20NZlvPr0EhH3EVegZlF/f3QIDAQAB;

spf.postal.example.com is literally an example.

You need to make spf.postal.amotic.net as a TXT record which references the main IP of your postal server and then make use of that.

Will:
Actually I have tested it that txt record
spf.postal and point to 45.76.210.83 but still failed of check records correct step, what's happened? is that godaddy DNS has some restriction on this?

[willpower232]

According to https://www.whatsmydns.net/#TXT/amotic.net the SPF record needs changing from spf.postal.example.com to whatever your SPF record for your postal is

I have modified it 3 mins ago, now may updated already.
I also confused with the dkim record setup.

[willpower232]

Your DKIM record looks right but you'll probably have to wait some hours before godaddy actually updates your DNS. You should wait a bit and then check whatsmydns.net again.

the problem is even DKIM record are right but unable to pass the check records correct internal of postal I have installed, that's why I am confused.

[willpower232]

your domain seems to be missing the SPF record entirely now, I'd suggest reviewing the domain names mentioned in postal.yml and studying the record check pages to make sure you have everything in place properly

[infooer]

nihao, You need to restart postal to get your postal.yml configuration content in effect...

@wuweifengsheng If you need installation service, let me know :)

Hello,
How to configure DNS server for Postal?
I need to install and configure Bind with Postal?

[igerzog]

You can do this in the control panel of your personal domain registrar. It is not necessary to install your own BIND server.
