WordPress uses PHPMailer to send mail from with your local mail server, but it can happen that your mail were not accepted by mail providers...\nThis can happen for several reasons, sometimes because the mail server is not configured or sometimes because the records DKIM, DMARC and SPF of the domain been set up correctly and so on...\nAnyway you can avoid any problems by using an external SMTP server and sending mail with it!<\/p>\n\n

Go to Google Cloud Console<\/strong> (console.cloud.google.com).\n2. Create a new project.\n3. Go to APIs & Services > Credentials<\/strong> and click Create Credentials > OAuth client ID<\/strong>.\n4. Application type: Web application<\/strong>.\n5. Authorized redirect URIs<\/strong>: Copy the URL from the plugin settings (e.g., Microsoft Office 365<\/strong>\n1. Go to the Azure Portal<\/strong> (portal.azure.com).\n2. Navigate to Azure Active Directory > App registrations > New registration<\/strong>.\n3. Enter an application name and set the Redirect URI<\/strong> (Web) to the exact URL provided in the plugin settings.\n4. Go to Certificates & secrets<\/strong> and create a new client secret. Copy the secret's Value.\n5. Go to API permissions > Add a permission > Microsoft Graph > Delegated permissions<\/strong> and add Would you like to find more presets (that you think are useful to other users)?\nOpen a request in the support form and provide the necessary connection data (auth, server address and port).\nIn the next cf7-smtp version you will find the required configuration among the presets.<\/p>\n\n It's warmly advised to use OAuth2 for supported providers (Gmail, Office365) so no passwords are saved. If using basic SMTP authentication, it is highly recommended to store at least the password into wp-config.php as a constant.\nAnd in addition, it's also very easy! It needs only to add<\/p>\n\n into your All passwords will be stored encrypted, but still it is not good practice to put it into database!<\/p>\n\n as with the user password other constants can also be defined.\nAvailable constant are CF7_SMTP_HOST, CF7_SMTP_PORT, CF7_SMTP_AUTH, CF7_SMTP_USER_NAME, CF7_SMTP_USER_PASS, CF7_SMTP_FROM_MAIL, CF7_SMTP_FROM_NAME<\/p>\n\n But, to quickly set up the plugin there is one constant that wraps all the others, so in case you manage multiple websites this will be very convenient!<\/p>\n\n Wouldn't it be better to have a small container to make our mail a little prettier?\nWell we have it! You can now assign specific templates to each of your forms via the plugin settings dashboard.\nTo use your own custom templates for emails, simply create them by following these steps:\n1. Create a folder named Community support: via the support forums<\/a> on wordpress.org\nBug reporting (preferred): file an issue on GitHub<\/a><\/p>\n\n We love your input!\nWe want to make contributing to this project as easy and transparent as possible, whether it's:<\/p>\n\n We use GitHub to host code, to track issues and feature requests, as well as accept pull requests.\nBy contributing, you agree that your contributions will be licensed under its GPLv2 License.<\/p>\n\n\nSMTP<\/h3>\n\n
