For instance, the body of an e-mail can be set by taking the results of other actions (like system messages, error messages, etc.), text data from a file, or data from any other backend system. Other e-mail parameters like the list of recipients may be generated from a database query. Furthermore, e-mails can be sent with attachments that may contain dynamic data.
POP3 Adapter and SMTP Adapter provide basic email receiving and sending. However, these adapters do not offer advanced features such as imap/imaps/smtps support, ssl/starttls encryption or folder access. In scenarios where such advanced features are required, we recommend the use of the JavaMail library.
