Simple usecase but doesn't work.
I have a web application and want to configure a SMTP server to send emails from application.
Installed mailx as per link - http://tecadmin.net/bash-mail-command-not-found/
All good.
Test Sending email as: echo "This is a test email body " | mail -s "This is a test email " dk#xxx.com
Now I get the following in logs :

All green, no errors, just as things seem to be too good to be true, I never receive this email in gmail.
What am I missing ?
Thank you,
First off, you can't send an email from localhost. You need a mail relay. Since you're already using gmail I would recommend this:

i've got a problem configuring sendmail to send email through smtp.
My goal is to have the ability to send mail from a php application using smtp.
I've to migrate to a new server some old legacy php application which use the standard "mail()" php function, and i can't modify the code, so i can't just use something like "phpMailer" or "pear mail package" instead.
I've followed this guide (venice answer) sendmail: how to configure sendmail on ubuntu? , and watched many other that say the same thing...
I've already installed and configured sendmail, and it works fine for sending local mail (if i send an email to root#localhost, i receive it correctly) but not for sending "normal" email..
Every time i send an email i've got these error in the mail.log file:

This is what i've initialy added to the sendmail.mc file
define(`SMART_HOST',`authsmtp.securemail.pro')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
FEATURE(`authinfo',`hash /etc/mail/auth/client-info')dnl
I've made some research and understood that the problem may be the port that sendmail is using for the smtp connection.
i've tried to telnet my isp and i'm able to contact it only on port 465, but i cannot find a way to change the port that sendmail is using.
I've tried to add those line, but with no luck:
define(`ESMTP_MAILER_ARGS', `TCP $h 465')dnl
define(`RELAY_MAILER_ARGS', `TCP $h 465')dnl
I've also noticed that one antoher server that i have with sendmal instaled and propely configured is using the mailer esmtp, this installation use insted relay, is that normal?
What i'm doing wrong?
Thank yuo in advance, hope that i've listed all the relevant details.
First find more info. Force delivery retry in verbose mode with SMTP session tracking.
It provides useful hints in most cases (well above 50% based on my experience).
To push email with queue id xAQEkfEJ016252 as root execute the following command:
sendmail -v -qIxAQEkfEJ016252
We have a perl script which tries to send an email notification when the system is about to shut down. To do this, we catch the SIGTERM and call Unix mail command to send email in the signal handler. SIGTERM is caught but the unix mail log shows that the FROM and TO address are changed from user#companyname.com to user#hostname during shutdown. Any idea why the system does this and how to prevent it? (Please note: The same email works fine when we run the script and kill the process from terminal)
Here is the perl code snippet:
$SIG{TERM} = \&signal_handler;
sleep(3600);
sub signal_handler {
my $email_address = 'user#companyname.com';
system("echo \"TestBody\" | mail -s \"TestEmailSubject\" -c \"$email_address\" -r \"$email_address\" \"$email_address\"");
}
Here is what is printed in /var/log/mail/mail during shutdown:

Here is the working case when we kill the process from terminal:

the postfix system is probably being shut down earlier in the shutdown process than your script. Have you confirmed within your script that the mail system is still up after your script has tried to send an email?
I am trying to send a mail with a non root user (also by tuleap application) but i have some trouble.

it return this log and my email is sent

Try to remove sendmail and install postfix instead. And tell me if it works better this way. You'll find how to do it here.
On our server, we keep receiving spam with the following headers. We are using whm 11.44 and exim.
Return path is always:
Return-path: <>
and it says Received: from unknown (HELO localhost)
Both which raise flags. We're just not sure exactly how to stop/reject them.

When I try to send an email as root using the following command, the email delivers successfully:
echo "Test" | sendmail -r user#mydomain.com myemail#gmail.com
But when I send an email, using the same command, as a different user, it does not deliver the email even though it's successful in the logs.
