how to fix this problem?
As the error states, The IP address sending this message does not have a PTR record setup, so you need to set the PTR record for 185.124.86.138 (it is quite usual that receiving mail server requires this). Reverse DNS is controlled by whoever "owns" the IP address, so you should probably contact Bilgehosting to set the record for you)

The error is as follows:
This is the mail system at host xxxxxxxxxxxxxxxxxxxxxxx.

Why is this happening?
Because Gmail doesn't just accept emails from any domain without autheticating them.
Research keywords SPF, DMARC & DKIM. They will lead you in the right path.

I don't have any idea about this can anyone please help.
Puzzling problem sending emails from one server to another.
Sending from Server-01 pr#example.camp TO Server-02 eman#example.edu.au
Server 02 bounces with sender verify fail for <pr#example.camp>: Unrouteable address
On Server-02 running dig MX example.camp resolves fine with:
;; ANSWER SECTION:
mus.camp. 2869 IN MX 10 server01-aus.emanwebdesign.com.
mus.camp. 2869 IN MX 0 server01-aus.emanwebdesign.com.
;; AUTHORITY SECTION:
mus.camp. 2869 IN NS ns10.domaincontrol.com.
mus.camp. 2869 IN NS ns09.domaincontrol.com.
Also from Server-02 I can telnet into port 25 of mus.camp and verify the existence of the email address (pr#...).
Any clues as to why Exim's sender verify is failing?
Edit
exim -bvs pr#example.camp returns
pr#example.camp failed to verify: Unrouteable address
Worked out the problem was that the mus.camp domain was originally hosted on Server-02 but then moved to Server-01. Server-02 however was still trying to lookup the email address within itself instead of going to Server-01.
To solve the problem I deleted the mail and dns records from Server-02. (using VestaCP).
I have Exim on server with test#domain.com email.
And now i'm sending email to test#domain.com from test2#domain.com but using provider SMTP and i'm getting following error:
Failed: test2#domain.com → test#domain.com 'Microsoft Office Outlook Test Message' Server response:
550 550 Verification failed for <bounce+2db7fb.5fc31-info=test#domain.com> Unrouteable address Sender verify failed
How can i put my SMTP (sender) to white list?
Have you correctly setup your domain MX record your server ? I think there is an issues with the mx record of your domain.
