SMTP is an internet standard for email transmission across IP networks that are typically only used for sending messages to a mail server for relaying.

The SMTP functions support two ways of sending emails.

smtp Send, for simple short messages:

• Only the smtpSend function is needed.
• The function waits for the mail transfer to complete.

• The function waits for the mail transfer to complete.
• Only a short text message.
• No attachments.

smtp SendX, for advanced messages:

• Large text messages.
• Message text can be built over time.
• File attachments.
• Asynchronous mail transfer (depending on the situation, this can also be a disadvantage).
• Mail transfer progress can be monitored.
