postfix email not working in Oracle Linux

vjy · 05-04-2015, 05:08 PM

I have setup postfix in Oracle Linux VM in virtualbox to test simple email sends that I am sending it to my personal email.

I have configured the following in main.cf file

myhostname = abc.testserver.org
myorigin = $myhostname
inet_interfaces = localhost
#relayhost = localhost.localdomain - I have this commented as of now, but I tried with the localhost.localdomain, IP address and none worked. I also do not have my ISP's server details and I also do not want to use it.

I checked the /var/log/maillog and I see the following

Code:

May  4 17:25:37 oim sendmail[31684]: t44LPbKA031684: from=root, size=72, class=0, nrcpts=1, msgid=<201505042125.t44LPbKA031684@localhost.localdomain>, relay=root@localhost
May  4 17:25:37 oim sendmail[31685]: t44LPbSn031685: from=<root@localhost.localdomain>, size=378, class=0, nrcpts=1, msgid=<201505042125.t44LPbKA031684@localhost.localdomain>, proto=ESMTP, daemon=MTA, relay=localhost.localdomain [127.0.0.1]
May  4 17:25:37 oim sendmail[31684]: t44LPbKA031684: to=abc@abc.com, ctladdr=root (0/0), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30072, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (t44LPbSn031685 Message accepted for delivery)

I can also see the messages in /var/spool/mqueue/. The telnet to the localhost 25 port also works. Is any of the config settings wrong?

Thanks.

So...you've got a VM system running, and have told it to accept email, and don't tell it HOW TO DELIVER THEM, and you don't know why it won't send??? Unless you define SOME sort of server upstream, be it a smart host or using your ISP's SMTP server, what do you expect it to do?? Unless you fully configure your server with an MX record, DNS, and everything else it needs to be a server.domain.com system, it has no way of delivering mail.

You've been using Linux for ELEVEN YEARS now...being able to read the documentation on postfix should be something you can do. Also, since you're using Oracle Linux (which is NOT FREE), have you contacted Oracle support for help????

Fair enough reply TB0ne. Even though I started with Linux 11 years ago, I did not work on it for the whole period and did not do anything admin related or installs.

Anyway, I was not sure if I could use my ISP server for testing and wanted to check if there is any other way.

But I just found another email server this afternoon that I am planning to use(devNullSMTP) and it accomplishes what I need to.

Thanks again.

Except for the questions you posted in 04, 08, and 10?

You can find out if you can use your ISP's server, by calling your ISP. And the "other way" is to configure a smart host or some other server to relay the messages to. Very obviously, unless you have some route/destination for emails, they won't go anywhere.

...and what it accomplishes is exactly what you already have with postfix/sendmail/mailx. What's the point in installing some slow Java program to duplicate that functionality??? Again, unless you define SOMEWHERE for that mail to go, it will only EVER be local.

Again, as said before: read the postfix documentation about configuring a single smarthost (very simple, and amply documented with examples), or use mailx, and just put your ISP info in the config file. And HAVE YOU CALLED ORACLE SUPPORT, since you're paying for it???
