Here’s a piece of code to send mail from Processing. It uses the net library. Warning: your mail server may not use port 25.
/* mail_client by Tom Igoe A simple mail sender client Created 21 January 2006 */ import processing.net.*; Client myClient; int clicks; String reply = null; boolean sent = false; void setup() { // Connect: myClient = new Client(this, "echonyc.com", 25); delay(300); } void draw() { if(!sent) { waitForReply(); myClient.write("HELO echonyc.com\n"); waitForReply(); myClient.write("MAIL FROM:tigoe@echonyc.com\n"); waitForReply(); myClient.write("RCPT TO:tigoe@echonyc.com\n"); waitForReply(); myClient.write("DATA\n"); waitForReply(); myClient.write("Subject:Noodles\n"); myClient.write("From:tigoe@echonyc.com\n"); myClient.write("To:tigoe@tigoe.net\n"); myClient.write("\rHere's the body\n.\n"); waitForReply(); myClient.write("QUIT\n\r"); waitForReply(); } sent = true; } void waitForReply() { int newChar = 0; while (newChar != 10) { if(myClient.available() > 0) { newChar = myClient.read(); reply += (char)newChar; } } println(reply); }
