- AUTHOR: Ryo Chijiiwa <ryo@ilohamail.org>
- FILE: include/smtp.php
- PURPOSE:
- Provide SMTP functionality using pure PHP.
- PRE-CONDITIONS:
- The functions here require a SMTP server configured to allow relaying.
- POST-CONDITIONS:
- The following global variables are returned:
- $smtp_errornum - error number, 0 if successful
- $smtp_error - error message(s)
- $SMTP_TYPE - Optional
- COMMENTS:
- The optional $smtp_message_file can be used for sending extremely large
- messages. Storing large messages in a variable will consume whatever
- amount of memory required, which may be more than is available if dealing
- with messages with large attachments. By storing them in a file, it becomes
- possible to read/send bits at a time, drastically reducing memory useage.
-
- This library only provides bare-bones SMTP functionality. It is up to the
- parent code to form valid RFC822 (MIME) messages.
