    Configure Postfix on this System For Sending Mails

    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@a bc.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:

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