Mailx sending all mails to spam folder.

  • Posted November 17, 2013

Newbie Here,

My goal is to setup email accounts with my domain (ex: and use the SMTP Server I configured in my NodeJS App to send mails to my app’s subscribers.

I followed this tutorial in setting up Postfix and Mailx:

and installed iRedMail following this tutorial:

All is working fine except that all mails from the email accounts are being sent to the spam folder.

I have set up a TXT Record with these values as instructed in the tutorial:

Name: @ Text: v=spf1 ip4:MYSERVERIP_ADDRESS -all

Check out <a href=“”>How To use an SPF Record to Prevent Spoofing & Improve E-mail Reliability</a>.

@Kamal Nasser This is the response I get: <br> <br>StartError <br>Context: Failed to query MAIL-FROM <br>ErrorCode: (2) Could not find a valid SPF record <br>Error: No SPF records for ‘’ <br>EndError <br>none

Here’s an example: <br><img src=“ from 2013-11-17 15%3A50%3A39.png” alt=“screenshot” />

because it says “Unable to resolve cjflores in the DNS”
