✉️SMTP Mailer

Create and send multipart MIME messages.

KSMTPMailer Class Overview

• MIME Multipart Message Creation Easily create MIME multipart messages with support for text, HTML content, and file attachments.

• Secure and Non-Secure Connections Supports STARTTLS/TLS (default) for secure communication and non-secured connections when required.

• Authentication Options Compatible with both OAuth 2.0 and basic authentication for flexible access to SMTP servers.

• Automatic MX Record Lookup If the SMTP host is not specified, automatically queries DNS for the highest-priority MX record.

• Enhanced Mail Header Automatically includes the X-Mailer header to identify the sending application.

For servers requiring OAuth 2.0 authentication, leverage the Simple OAuth 2.0 Framework for Authentication (Freeware) to obtain access tokens efficiently and securely.
