Simple SMTP vs WPO365 | MICROSOFT 365 GRAPH MAILER

Adds a simple, no-fuss SMTP settings to your WordPress installation that lets you define custom settings, which is especially useful for hosts with no control over the php mail functionality. If logging is enabled, a new segment in the settings panel will show up with a 30-day overview of recent emails, and will automatically prune older logs. Please see the FAQ if you want a more permanent solution. For more information, please see the project wiki on GitHub. Environment and constant overriding (optional) This plugin will prefer environmental and constant-stored values over the plugin-saved equivalent settings, making it easier to use this plugin via deployment. These can be either stored in your systems env setup, or in wp-config.php as define( 'SEE_BELOW', 'your_value_here' );. Accepted Parameters SMTP_HOST (string) Mail server hostname. SMTP_PORT (integer) Port address (usually 25, 465 or 587). SMTP_AUTH (integer, 1 or 0) 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’, ‘tls’ and ‘off’). SMTP_NOVERIFYSSL (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. It is recommended to store at least SMTP_PASS in your wp-config.php file (with the correct file permissions set). If the openssl extension is available, the plugin will attempt to encrypt the password in the database.

WPO365 | MS GRAPH MAILER provides you with a modern, reliable and efficient way to send WordPress transactional emails from one of your Microsoft 365 / Exchange Online / Mail enabled accounts. The plugin re-configures your WordPress website to send emails using the Microsoft Graph API instead of – for example – SMTP. Sending WordPress emails using the Microsoft Graph API has become the only available alternative after Microsoft has disabled basic authentication (username and password) over the SMTP protocol. DELIVERY Send WordPress transactional emails from one of your Microsoft 365 Exchange Online / Mail enabled accounts using Microsoft Graph instead of – for example – SMTP. Choose between delegated (send mail as a user) and application-level (send mail as any user) type permissions. Or: Select either a Microsoft 365 account or a personal Microsoft account, like Hotmail.com or Outlook.com, to send WordPress emails. Or: Configure RBAC for Exchange Online and authorize as an application but with a limited scope e.g. one specific mailbox. SEND AS HTML Send emails formatted as HTML. SAVE TO SENT ITEMS Emails sent will be saved in the account’s mailbox in the Sent Items folder, further helping to track (successful) mail delivery. ATTACHMENTS Send files from your WordPress website as attachments. WPO365 INSIGHTS See what matters, when it happens Track key WPO365 events like sent emails with WPO365 Insights more CONFIGURATION / TEST EMAIL DELIVERY Easy configuration with detailed step-by-step Getting started guide and video.
