Emails · 4D Documentation

Creating, sending or receiving emails in 4D is done by handling an Email object. This object is used by the following commands and methods:

SMTP - .send() function to send an email through SMTP
POP3 - .getMail() function to get an email from a POP3 server
IMAP - .getMail() and .getMails() functions to get emails from an IMAP server.
MAIL Convert from MIME and MAIL Convert to MIME commands to convert emails

Email Addresses

All properties that contain email addresses (from, cc, bcc, to, sender, replyTo) accept a value of text, object, or collection type.

Texte

single email: "somebody@domain.com"
single display name+email: "Somebody somebody@domain.com"
several emails: "Somebody somebody@domain.com,me@home.org"

Objet

An object with two properties:

Propriété	Type	Description
name	Texte	Display name (can be null)
email	Texte	Email address

Collection

A collection of address objects.

Handling body part

The textBody and htmlBody properties are only used with the SMTP.send() function to allow sending simple mails. When both property are filled, the MIME content-type multipart/alternative is used. The email client should then recognize the multipart/alternative part and display the text part or html part as necessary.

bodyStructure and bodyValues are used for SMTP when the Email object is built from a MIME document, e.g. when generated by the MAIL Convert from MIME command. In this case, both bodyStructure and bodyValues properties must be passed together, and it is not recommended to use textBody and htmlBody.

Example of bodyStructure and bodyValues objects

"bodyStructure": {
  "type": "multipart/mixed",
  "subParts": [
    {
      "partId": "p0001",
      "type": "text/plain"
    },
    {
      "partId": "p0002",
      "type": "text/html"
    }
  ]
},
"bodyValues": {
  "p0001": {
    "value": "I have the most brilliant plan. Let me tell you all about it."
  },
  "p0002": {
    "value": "<!DOCTYPE html><html><head><title></title><style type=\"text/css\">div{font-size:16px}</style></head><body><div>I have the most brilliant plan. Let me tell you all about it.</div></body></html>"
  }
}
