having isssues with sending mail from my server to gmail

[astralsourabh]

Hello

Since many days i have been facing issues with the emails, ie whenever mails are sent / forwarded from my server ( in case a email account has forwarder set to @gmail) , gmail always rejects message and i get something like :

"SMTP error from remote mail server after end of data: host gmail-smtp-in.l.google.com [173.194.66.27]: 550-5.7.1 [My server ip] Our system has detected that this message is\n550-5.7.1 likely unsolicited mail. To reduce the amount of spam..."

I have the following setup :-

1) Server host is set as :- serverone.xxxx.co.uk (domain removed) My domain mail is hosted on google apps for domain and the server's main contact email (WHM/Cpanel) also belongs to this domain.

2) I have Set DKIM signatures and SP records too.

3) however when i run dig -x 109.228.12.240
i get 240.12.228.109.in-addr.arpa. 21599 IN PTR server109-228-12-240.live-servers.net.

4) While diagnosing the failed email i have found that many email that gets rejected have
Sender IP: ::1
Router: dkim_lookuphost
Transport: dkim_remote_smtp

5) Also some accounts that are using Google mx, they don't even get mails, however while checking mail delivery reports they have status as "Message accepted" and Transport "remote_smtp"

Please help , iam struggling to get the solution, we are getting lots of complaints from our customers.

Thanks in advance.

Hello

To clarify, are you having problems sending email to Google? You reference the bounce from Google, but also mention that some of your accounts are not receiving email. Note that Google provides the following document for information on how to ensure you are not blocked:

Hello

Thanks for the quick reply..

Yes iam having problems sending email to Google and some accounts who are using google apps for business (Gmail) they don't receive mails on their gmail accounts , however while checking mail delivery reports they have status as "Message accepted" and Transport "remote_smtp".

Also i have checked https://support.google.com/mail/answer/81126 , but iam unable to fix the issue.
Only thing which i feel might be an issue is the PTR , as server mail server is set to serverone.xxxx.co.uk (domain removed) and the PTR record is server109-228-12-240.live-servers.net .

You could contacting your data center to have them update the PTR record to match the hostname of your server.

Thank you.
