Development process: 1.2010.09.14 Since the customer needs to send emails in the form of html source code, a single email is established. The system that supports html source code solves the input encoding problem and solves the problem that the email cannot be read after inputting the source code. 2. The customer wants to send the same email to multiple people, so the first version of small batch mass sending was created 3. The customer has multiple email accounts and has set up a program to configure the email account. The customer can change the SMTP account for sending. 4.2010.09.15 Optimized the mass sending program, created a waiting prompt box, and set the interval for sending emails to prevent recipients from being blocked by the mail server to the greatest extent. Due to the limitations of PHP, this small batch sending is subject to the limitation of PHP program execution time and cannot send large amounts of emails. 5.2010.09.15 Created a program for sending bulk emails without restrictions. 6.2010.09.16 Removed the bug of small batch mass sending Further optimization of future version functions of the mass-sending program: Adding an html online editor can create beautiful emails for sending online. It can read the txt email address list for sending and randomly read and send the SMTP account for sending function to prevent the recipient's mail server from being blocked to the greatest extent.
