Settings Overriding

This plugin supports being overridden by DEFINE, so please check to see that you are not setting a define for a WP Simple SMTP option. These are most commonly stored in the wp-config.php file.

Settings Table

These can be either stored in your systems env setup, or in wp-config.php as:

define( 'SEE_BELOW', 'your_value_here' );

Variable	Type	Description
SMTP_HOST	string	Mail server hostname.
SMTP_PORT	integer	Port address (usually 25, 465 or 587).
SMTP_AUTH	integer	Pass below credentials to your mail server.
SMTP_USER	string	The mail username for this account.
SMTP_PASS	string	The password for the mailer account.
SMTP_FROM	string	Enforce all emails come from this email address.
SMTP_FROMNAME	string	Enforce all emails to have a certain email name.
SMTP_SEC	string	Use a particular email security method (accepts 'def' (default), 'ssl' and 'tls').
SMTP_NOVERIFYSSL	boolean	(boolean) Disable validation of the SMTP server certificate (not recommended).
SMTP_LOG	boolean	Controls the logging capability and visibility.
SMTP_DISABLE	boolean	Disables the mailer. They will still be logged if enabled, but won't send out.

Overriding Hierarchy

The over-ride hierarchy is as follows, with top being the most important.

• Environmental variable.

• Multisite network settings.
