SMTP65.SYSTEM

Run using Open Apple-S in EMAIL.SYSTEM

SMTP65

SMTP65.SYSTEM is a Simple Mail Transport Protocol (SMTP65) client for the Apple II. It requires an Uthernet-II ethernet card and will not work with other interfaces without modification, because it uses the W5100 hardware TCP/IP stack. SMTP65.SYSTEM is used to send outgoing email messages to an SMTP email server. (I use Postfix on the Raspberry Pi as my SMTP server, but other SMTP servers should work too.)

Before running SMTP65.SYSTEM for the first time, be sure to have created the SENT mailbox. This must be a 'proper' mailbox, not just a directory. You may create a mailbox using the N (new mailbox) command in EMAIL.SYSTEM.

SMTP65.SYSTEM performs the following tasks:

  • Detect Uthernet-II
  • Obtain IP address using DHCP
  • Connect to SMTP server using parameters from lines 5 and 6 of EMAIL.CFG. (HELO command)
  • Iterate through each message in the OUTBOX mailbox (which is /H1/DOCUMENTS/EMAIL/OUTBOX with our sample configuration)

    • Scan each message looking for the following headers:

      • To:
      • From:
      • cc:

    • Prompt S)end message | H)old message in OUTBOX | D)elete message from OUTBOX

    • If the user chooses D then delete the message from OUTBOX and contine to the next message (if any).

    • If the user chooses H then retain the message in OUTBOX and contine to the next message (if any).

    • If the user chooses S then proceed to send the message to the SMTP server, as follows:

      • Notify the SMTP server of our email address (from EMAIL.CFG). (MAIL FROM: command)
      • Notify the SMTP server of each recipient listed in To: and From: headers (RCPT TO: command)
      • Send the email body to the SMTP sender. (DATA command)
      • If the message was successfully sent, copy it to the SENT mailbox.
      • Remove the sent message from OUTBOX.

    • Iterate until all messages in OUTBOX have been sent, and copied to SENT. Rejected messages are left in OUTBOX where they may be edited and retransmitted.

    • Issue QUIT command to SMTP server to disconnect.

  • If SMTP65.SYSTEM was invoked from EMAIL.SYSTEM, load and run EMAIL.SYSTEM. Otherwise quit t o ProDOS.
