Frequently Asked Questions
Common questions about Post SMTP – Complete Email Deliverability and SMTP Solution with Email Logs, Alerts, Backup SMTP & Mobile App
A modern replacement for traditional password-based authentication. Post supports the OAuth 2.0 implementations of all three major e-mail providers: Gmail, Office365, Brevo, Mailgun, Hotmail and Yahoo Mail.
Post requests a limited access OAuth 2.0 token (valet key) to access the APIs (enter the house) and perform a specific service (handle Gmail SMTP, stay out of Google Docs) with no need for you to surrender your username and password credentials (master house key). Once access is granted, Post commandeers the WordPress wp_mail() function to provide an incredibly stable mail sub-system. There are many reasons why OAuth 2.0 is better than any password-based mechanism: Post will never ask for your password, so your password can't be stolen If you change your password regularly, you will never have to update Post's configuration You have tighter control over the data Post has access to. For Google users, it can never access your Calendar or Docs or YouTube; for Yahoo users, it can never access your Flickr If your WordPress site gets hacked, you can revoke Post's email access without impacting any other application or website that has access to your account NEVER give out your Gmail, Microsoft or Yahoo password to a 3rd-party or 3rd-party program that you don't fully trust.
Yes! With the Post SMTP Plugin, you can configure any SMTP mailer account, including Brevo, Mailgun, and SendGrid on your WordPress site. Check out our detailed SMTP configuration documentation for all major SMTP service providers.
To use OAuth, your website needs its own Client ID. The Client ID is used to control authentication and authorization and is tied to the specific URL of your website. If you manage several websites, you will need a different Client ID for each one.
Go to Microsoft account Developer Center and select 'Create application'. In the 'Application name' field, enter 'Post SMTP'. Select 'I accept.' Select 'API Settings' from under 'Settings'. In 'Redirect URL', enter the redirect URI given by Post (either from the wizard or from the manual configuration page). Select Save. Select 'App Settings' from under 'Settings'. Enter the Client ID and Client Secret displayed here into the Post's settings page.
Go to Yahoo Developer Network and select 'Create an App'. In the 'Application Name' field, enter 'Post SMTP'. For 'Application Type', choose 'Web Application'. In 'Home Page URL', enter the 'Home Page URL' given by Post. In 'Callback Domain', enter the 'Callback Domain' given by Post. Under 'API Permissions', choose 'Mail.' Under 'Mail' choose 'Read/Write' Click 'Create App' Enter the Client ID and Client Secret displayed here into the Post's settings page.
If you have a Google Account from the Google Developer's Console, use the Delete button under the Client ID. If you have a Microsoft Live account, from the Microsoft account Developer Center, select the Application and choose Delete Application. If you have a Yahoo Account, from the Yahoo Developer Network My Apps, select the Application and choose Delete App.
