relayhost = [SMTP_SERVER_NAME]:587 smtp_tls_security_level = encrypt smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = noanonymous |
In the above, replace SMTP_SERVER_NAME with your Amazon SES mail server, for example “email-smtp.us-east-1.amazonaws.com”, you can see it in your Amazon SES console.
Run
|
1 |
echo "[SMTP_SERVER_NAME]:587 SMTP_USERNAME:SMTP_PASSWORD" > /etc/postfix/sasl_passwd |
Replace SMTP_SERVER_NAME, SMTP_USERNAME and SMTP_PASSWORD with your actual credentials.
Now run
|
1 |
postmap /etc/postfix/sasl_passwd |
Restart postfix
|
1 |
service postfix restart |
You can test mail working with
|
1 |
echo "test" | mail -r you@SES_VERIFIED_DOMAIN -s "test" admin@serverok.in |
For sending from Apache, you may need to set myorigin in postfix confgiration with your veirfied domain. This can be done by editing
|
1 |
vi /etc/mailname |
You can verify myorgin with
|

root@ip-172-31-30-228:~# postconf | grep myorigin append_at_myorigin = yes myorigin = /etc/mailname root@ip-172-31-30-228:~# |
