Configure SMTP for outbound emails
To configure outbound emails from CiviCRM, follow these steps:
Log in to the Drupal administration console as an administrator.
Browse to the CiviCRM administration console and select the “Outbound Email Settings” item.
Select “SMTP” as the mailer.
Enter the following configuration options using the information below as a guideline. This example configures a Gmail account. Replace USERNAME and PASSWORD with your Gmail account username and password respectively.
SMTP Server - ssl://smtp.gmail.com SMTP port - 465 Authentication? - Yes SMTP Username - USERNAME@gmail.com SMTP Password - PASSWORD
Click “Save and Send Test Email” to verify that it all works. To configure the application to use the SMTP service provided by Amazon Simple Email Service (SES), refer to the guide on using Amazon SES.
NOTE: Amazon EC2 blocks SMTP port 25 by default on all Amazon EC2 instances, and you must manually request removal of this restriction to use this port.
To configure the application to use other third-party SMTP services for outgoing email, such as SendGrid, refer to the FAQ.
NOTE: If you are using Gmail as the outbound email server, your application’s attempts to send outgoing emails may be blocked by Gmail if it considers the authentication attempts to be suspicious. When this happens, you will receive a Gmail security alert at the corresponding Gmail address. To proceed, you will need to manually confirm the validity of the authentication attempt before Gmail will permit the application to send outbound emails. For more information on this and other Gmail issues related to outbound email from your application, refer to our Gmail SMTP troubleshooting page.
