How to send bash script output via email using AWS SES

• Create SES SMTP user

https://console.aws.amazon.com/iam/home?#/s=SESHome

We need

SMTP Username:
AXXXXXXXXXXXXQ
SMTP Password:
AsFbCCCXXXXXXXXXXXCXXXXXXXXXXXqQ6

• Validate email to send FROM

SES - Email Addresses - Verify a New Email Address

• Create custom policy in IAM in order to give permissions to send emails and assign to a role. Assign role to instance.

{

    "Version": "2012-10-17",

    "Statement": [

        {

            "Effect": "Allow",

            "Action": [

                "ses:SendEmail",

                "ses:SendRawEmail"

            ],

            "Resource": "*"

        }

    ]

}

• install mailx package ( yum install mailx) and test it :

-v verbose

-s Subject

-S settings

-S nss-config-dir can be found by  find / -name "cert*.db", /etc/pki/nssdb/ in my case

-S from "EMAIL@VALIDATED.DOMAIN" - watch step 2

mailx -v -s "Test" -S smtp-use-starttls -S ssl-verify=ignore -S smtp-auth=login -S smtp=smtp://email-smtp.us-east-1.amazonaws.com:587 -S from="EMAIL@VALIDATED.DOMAIN" -S smtp-auth-user=AXXXXXXXXXXXXQ -S smtp-auth-password= AsFbCCCXXXXXXXXXXXCXXXXXXXXXXXqQ6 -S nss-config-dir=/etc/pki/nssdb/ USER@DOMAIN.RECIPIENT

• Edit global mailx conf (/etc/mail.rc)  and add account: 

account ses {

        set smtp-use-starttls

        set ssl-verify=ignore

        set smtp-auth=login

        set smtp=smtp://email-smtp.us-east-1.amazonaws.com:587

        set from="EMAIL@VALIDATED.DOMAIN"

        set smtp-auth-user= AXXXXXXXXXXXXQ

        set smtp-auth-password= AsFbCCCXXXXXXXXXXXCXXXXXXXXXXXqQ6

        set nss-config-dir=/etc/pki/nssdb/

}

• Test mailx global config

echo -e "Test Mail body text" | mailx -v -s "Test" -A ses USER@DOMAIN.RECIPIENT

• Create script and add it to cron
