Configure Postfix on this System For Sending Mails

SUSE Public Cloud Amazon-EC2
1

Hi All,

I have a system running with Suse Enterprise Linux VERSION=“12-SP3”

VERSION_ID=“12.3”

PRETTY_NAME=“SUSE Linux Enterprise Server 12 SP3”

ID=“sles”

ANSI_COLOR=“0;32”

CPE_NAME=“cpe:/o:suse:sles:12:sp3”

We are also running the " open suse". We normally sending the mail to the client through java code and send mail configuration file in open suse and its working fine but once we deploy the same file in “SUSE Linux Enterprise Server 12 SP3” mail configuration is not working.

Below is the Sending mail configuration file

#Send mail configuration
sendemail=example@abc.co
sendemailpassword=
sendemailhost=smtp.zoho.com
sendemailport=465
sendemail.smtp.auth=true
sendemail.smtp.startssl.enable=true
sendemail.subject=User Creation Notification
sendemail.template.path=/particle/conf/EmailTemplate.html
sendsms.template.path=/particle/conf/UserSMSTemplate.txt
#Assessment Properties
assessemnt.qualification=50
#Generate Certificate
certificate.certificateimage=/particle/Certificate.jpg
certificate.lavaimage=/particle/lava.png
certificate.certificatepath=/particle/certificates
#HUL Properties.
sendnotification.toemailids=sample@abc.co,sample@abc.co
sendnotification.ccemailids=
sendnotification.bccemailids=
sendnotification.phonenumbers=
sendnotification.subject=

And also I would like to configure postfix on this system for sending mails as a root user using “mail” command to smtp server which will then forward it to the correct address.

Example " xyz# mail xyz@stupa.co"

As per my knowledge there are two main configuration files in /etc/postfix folder;

main.cf
master.cf

Can anyone help me out what setting needs to be done for sending the mails to my smtp server from SUSE Linux Enterprise Server 12 SP3 system.

What do you see on the wire when you try to send a message? Your “java
code” should not care about the distribution at all, so if the properties
file below is for that program then it sounds like something about that
program is not working, or perhaps something about the environment where
it is running.

For example, if your new SLES system is running in AWS (as I presume from
this forum) but you have a different security group (AWS firewall)
applied, then it may not be allowed to reach out to the world on TCP 465
to get the mail to smtp.zoho.com at all, even though the application is
trying, and the host is trying.

My brand new SLES 12 SP3 box in AWS’s EC2 has Postfix running by
default,so unless you have disabled it I do not think it should be
stopped/disabled.

You should not need to do much to just make it send e-mail outbound as
that is default functionality. On my EC2 instance, for example, I just
ran this command and sent myself a message:

echo 'This is a simple mail test.' | mail -s 'testing e-mail from
a2btech.com' aburgemeister@gmail.com

Good luck.
