I m using free zoho mail client application (similar to microsoft outlook) on my mobile [android / ios] for all my emails to mohtashim@techx.com
I wish to only recieve emails from my Linux Server details of which are: techx 3.10.0-514.10.2.el7.x86_64 #1 SMP CentOS release 7.3.1611 (Core).
I try the below command to shoot an email from the Linux server to my zoho mail client's mohtashim@techx.com email id but the email does not show in my inbox.
As soon as i fire this email command, the logs tail -f /var/log/maillog shows the following msg:
You could try to connect to port 25 in telnet. If you can connect from a different machine, it's obviously not firewalled. If you can't connect even from the same machine, port 25 isn't being listened for.

I m able to telnet successfully to port 25,587 & 465 from a remote system.
Also, locally all the ports seems to be listening as shown below.
So, i don't think there is any issue with the firewall.
Can you please tell me what could be the issue with the sending of emails?

You mention you've got your smart relay configured in sendmail.mc, but I wonder if it's actually gone live in your sendmail.cf (the real config file which is generated from the first one).
Could you see what output you get returned for:
please (assuming that's the location of your sendmail.cf, naturally) ? Also, have you re-started Sendmail since you put the smart relay in place ?
Just a thought, as a discrepancy between your .mc and your .cf could potentially explain why Sendmail appears to be ignoring your smart relay, so to speak.

Here is the Output after restarting the smtp service
Here is how I compile my /etc/mail/sendmail.mc
This is how i then restarted the smtp service
This is the command i use to send the email from the same server.
This is what i see in the mail logs.
Like i said before the mail is received locally by mohtashim user which can be checked using the mail command but the issue remains. The message is not delivered to the zoho email client configured on my mobile.
Here is the entry for /etc/mail/access
I am able to receive all other emails but not the ones triggered / send by the server.
Can you please suggest where the problem lies ?
