OK... we need more information then what you have provided. What do you have set in your DNS settings? Are you using the DNS server that's with Plesk or you using a third party DNS provider? What does MXToolBox show?

 

[NIEL]

under dns setting i have disabled and using cloidflare dns

what else tests require

 

[scsa20]

You're still not showing your SPF DNS entry, which would be in a form of TXT record. For example, the SPF record for me is a TXT for @ (root host) with the content of:

v=spf1 ip4:45.33.39.160 ip4:192.53.124.213 include:spf.protection.outlook.com -all

Since Google is complaining that you don't have a SPF record tells me you don't have that DNS entry added.

If you don't know how to make one, you can use something like Generator - SPF-Record to help generate one for you.

 

[NIEL]

check now
v=spf1 +a +mx +a:server.mydoamin.com -all

Please send an email elsewhere where it can be received, then look into the email headers (the invisible part with all the route information that the mail took through the internet) and provide it here. I am specificially interested in the first two hops from where the email is generated. I suspect that it is sent from a local script with a "wrong" address such as host 127.0.0.1, for example due to a missing "myhostname" entry in /etc/postfix/main.cf.

yes iam sending mail via my php script which is getting failed but via plesk webmail all are going correctly.
should i change below one to my ful domain in main.cf
#myhostname = host.domain.tld
#myhostname = virtual.domain.tld

 

[Peter Debik]

Yes, that should be changed to the name of your host. Not your subscription or website domain name, but the name of the whole server. Also the "#" must be removed, so that this no longer is a comment, but becomes an active entry. Postfix needs to be restarted afterwards.

i did it but still same error i changed to my server name and restarted server too stilll same error

[Peter Debik]

This is for sure a good thing. Let's move on to the other point: Headers of your mail. The reason why the recipient cannot see an SPF entry is hidden in that header. I'd still need to see the first two hops. You can also present the full header and redact sensitive information such as domain names.

 

[NIEL]

@Peter Debik
how do i collect header information for sent mail.

 

[NIEL]

i found this from bounce back email header from gmail.

I think that your script is adding the recipient line twice to the header. That is why GMail claims "550-5.7.1 duplicate To headers". I've not yet heard of a plugin named "xblast", but according to the headers you have one. Maybe you can replace it with another SMTP mailer plugin.

 

[NIEL]

thanks for finding the error we fixed it by removing it..

Hi NIEL

I am still not getting the email.
I can receive email in the disposable email service (Mailinator) but not in gmail inbox from ionos and plesk hosting.
Can you help me?
