Problem in receiving Email

RedRock

There is an issue occuring in getting the email on the server. There is no issues in sending an email from the server.

When someone sends an email, in postfix, it is written that the email is recorded and received but then it gets bounced and removed. This has happened multiple times. The given reason is that the sender in unauthenticated. I have tried to send test email from my own Gmail Id but the result remains same. Please suggest any solution.

I have given the error below.

RedRock There is no issues in sending an email from the server.

The error message above originates from the Google MX, so you have a problem in sending emails!

The error message indicates that your SPF record is wrong

You have some kind of error in your SPF or DKIM, send us you domain, so we can check your settings.

DocFraggle I apologize, I have misspelled the domain name. It’s theredhawkintl.com

DocFraggle

Ok, that one looks ok to me… so please post the error message from Google without redacted content to check it further

DocFraggle the error is not from google. Mailcow server postfix log shows the below error

[unknown] there is no problem in sending an email from Gmail to the server. There is no error shown in Gmail. Ratehe6the problem is arising in server where the email is received and then bounced, removed.

RedRock the error is not from google

Of course this is from Google! You are trying to send an email to a Gmail email address, and the Google MX is blocking it because of DKIM/SPF

Make a search for 873B4BB36C, it’s ID of message and preferably post here all your findings, this log does not contain from= because it’s response from gmail, we need log about you sending to gmail.

What to do to clear that error?

Uff bad resolution any chance to fix it?

There is another ID 907…. referencing your message look for this one too

RedRock

The log of ID 90766bb35d and the log of email sending.

Sorry man, other than google for some reason does not see your SPF record. I do not have explanation. Any chance you just change your DNS settings and you need to wait a while to wait on prune of DNS cache on Google side? (up to 24 hours)
