Hi guys, I'm facing a problem with my server and Gmail.
Here we have something about 50 email accounts and some of them use the Thunderbird to receive and send emails, others use the webmail RoundCube and others use Gmails to do this job.
The problem is that the people who use Gmail when sending an email to another one that uses Gmail to manage the account get a warning that says:
This may be a spoofed message. The message claims to have been sent from mydomain.com.br, but Gmail couldn't verify the actual source. Avoid clicking links or replying with sensitive information unless you are sure who is actually sending this message.
But if they receive an email from Thunderbird or RoundCube this message doesn't appear.
In the message in source of the message in Gmail it shows:
Code:
Authentication-Results: mx.google.com;
       spf=softfail (google.com: domain of transitioning [email protected] does not designate xxx.xxx.xxx.xxx as permitted sender) [email protected]
Received-SPF: softfail (google.com: domain of transitioning [email protected] does not designate xxx.xxx.xxx.xxx as permitted sender) client-ip=xxx.xxx.xxx.xxx;
My SPF configuration actually is:
Code:
v=spf1 +a +mx +ip4:xxx.xxx.xxx.xxx ~all
I don't know if I have to permit Gmail to send emails in the SPF or another way. Because it worked very well, and in the last month it begins to return this message. It's not a problem at all but it's annoying.
I'm sorry if I expressed the problem badly. And thanks for your help with it.

The first thing I would start with checking DMARC, DKIM, and SPF Records, ensuring these are correctly set for the domain name.
