Projects / smtp-cli


smtp-cli is an SMTP command line client with support for advanced features such as STARTTLS, SMTP-AUTH, or IPv6. It also has scriptable message composition capabilities supporting anything from simple plain-text messages right up to building complex HTML emails with alternative plain-text part, attachments, and inline images. It's also a convenient tool for testing and debugging SMTP servers' setups. smtp-cli can be used to check a given server's capabilities, to test your server's setup, or to create and dispatch email messages. The command line interface is intuitive, and everything is scriptable and can run in a completely non-interactive mode from scripts or cron jobs. smtp-cli is ideal for shipping log files from remote machines, running periodic mail delivery test loops, etc.

    Release Notes: Message building is now fixed for the case of plaintext with an attachment. AUTH is automatically enabled as soon as the --user parameter is used. Previously, --enable-auth or --auth-plain had to be used together with --user, which was confusing. The --print-only parameter was added for displaying the composed MIME message without sending. Non-standard modules are now optional. The local and remote addresses are displayed on a successful connect.
