Failing to connect smtp server

[Ahamed Husain]

Successfully configured SMTP server per steps given below

- Entered SMTP Name: 'smtp.example.com' under cpanel > exim configuration > mail > smarthost name
- Added required values in Exim configuration > mail > Advanced Editor > Section: POSTMAILCOUNT | Section: Auth | Section: Transportstart as instructed by: - Removed -| Please turn on SMTP Authentication

Through the above steps, attempted to send mail vide url: - Removed - But it failed throwing up the error that :"connection to the smtp server failed".

Seek your intervention as to enable sending mail flawlessly right into the inbox

Now smtp was connected successfully and phpmailer script displays message:mail is sent, but still client (gmail) has not received it either in inbox or spam. What shall we do .

 

[Ahamed Husain]

Here is an update. Local SMTP relay is working fine. PHPMailer is sending mails successfully but the remote client (like gmail) is not receiving. In WHM, The Mail Queue Manager shows frozen as status. And mail delivery report show as a 'remote host address is the local host'. Screenshot tagged herewith for ready reference. Help sorting out, revert.

Hello @Ahamed Husain,

Can you let us know the output to /var/log/exim_mainlog when reproducing this issue? EX:

exigrep [email protected] /var/log/exim_mainlog

Also, is the domain you are sending email from listed in the /etc/localdomains file or the /etc/remotedomains file?

Thank you.

Here below is the exim you asked for.

[[email protected] ~]# tail -f /var/log/exim_mainlog | grep [email protected]

2018-11-21 21:17:53 1gPUjJ-0000vz-51 == [email protected] R=remoteserver_r oute defer (-1): remote host address is the local host

The [email protected] is user to which our server ([email protected]) is sending mail to.

Additionally we have attached the screenshot of command.
To be upfront, we are not actually proficient in root terminal commands. So regret for any inadequate information.

Yes our domain is listed in /etc/localdomains file.

remote host address is the local host

Hello,

This error can sometimes indicate that your server's hostname is not a fully-qualified domain name? Can you confirm that the hostname of this server meets the requirements we document at the link below?

Thank you.
