I am running CentOS 7.3 on a VPS remote server. I have set up Postfix, Exim, and qmail. Dovecot & SSL active. All installations & configuration as per source documentation. They all, Postfix, Exim, and qmail, work (one at a time enabled) sending mails to & receive mails from local users. Mails to external users get sent with no error messages but are not received at destination mailbox. I have tried with SELinux enforcing & disabled. Firewall enabled & disabled. All required tcp ports open. Can anybody help please ?

We note your ability to set up mailers.

With qmail, the above is your problem. DJB is a networking genius. To quote John Dryden

I'll refrain from frank opinions on a moderated forum; the user is not at the forefront of concerns in the case of qmail. You are better following the site I gave you.

Do you have a valid domain? Also does the MX record points to your mailerver? What gives

Code:

dig mx yourdomain.com

You should also check the logs (usually /var/log/maillog), to see if you find something

I sincerely appreciate your reply and enjoyed the quote & and the implied transfer too :-))

Yes, I have a valid domain name. I had not tried dig. Will do so and get back to you

For a frank unmoderated opinion, I can post my mail id ;-))

Frivolities apart, could you please help me sort it out with postfix ?

Thank you with regards

LWQ is a good resource. Please also look at https://qmail.jms1.net/

If email is sent with no errors or BOUNCEs, then they are received, by definition... Are you sure there were no errors? Are the outbound messages queued? Does

Code:

qmailctl queue

work on your installation? If not, run

Code:

qmail-qstat
qmail-qread

to see if the outgoing messages are queued...out of the box, qmail will wait 7 days before telling you that an email can't be delivered (that can be shortened...see LWQ or DJB documentation, or ask how here...)
In a LWQ/JMS/typical installation, the send logs are at /var/log/qmail/* cat /var/log/qmail/current (or tail -f as you send mail) to see what's actually happening.
