The version numbers I use are somewhat unique. This particular one represents the Year, Month, Date, and sequence. June 6 2026 sequence 1: 2026.6.6.1. In my opinion, it's easier to track.

Here's the changelog for this latest version:

- now supports base64 encoded images in- $mail(); equivalent to $mail->send(SMTP);

It's not as easy as it seems.

If you take a look at all of the allowable characters for the local part of an email address, the commercial at sign (@) is one of them. That means that an email address like:

first@last@example.com 

is a valid email address. If you do the standard explode, you'll get three parts, not two. A typical function would  […more]

When I initially wrote the new PHPMailer Pro, the goal was to make it as user friendly as possible. Looking through support requests, many of the new features included detection of the mail server, port, and protocol. 

Much of the challenge was around user input of email addresses. Much of the issues were based on:

• input name first email address second, or is it email  […more]

I am in process of writing a new email address handling module for a new project that will eventually end up in PHPMailer Pro.

The process is underway with a good portion of the code written and testing underway. Just as this is ongoing, I received an email questioning a previous article about email address security. You can read two articles I wrote about security at […more]

One aspect of sending emails to a small or large email list is passing the email addresses to the mail transport, like PHPMailer Pro.

PHPMailer Pro handles it nicely with the ability to take email addresses in any of four formats:

• Strings, with the option of multiple email addresses separated by a comma
• Indexed Arrays, with the array key as a  […more]

PHPMailer-FVE is nearly here. The code is actually complete, we're just building a few sample forms and doing more testing along the way.

What is it? What is PHPMailer-FVE? All these acronyms ... FVE meansFormValidate andEmail. It combines two other of my projects (FormValidator and PHPMailer-FE - or Form2Mail).

It's actually ready […more]

On February 26, I wrote an article that included answering a question from a user. 

The question was about merging Form Validator and PHPMailer-FE. 

I use Form Validator extensively. Every form ever implemented by me (individually) or my company used Form Validator. 

It's 2024 and collecting information from your website users is even more risky today than ever. […more]

Form Validator came about quite some time back. It is the result of my company's need for highly secure forms. At the time, we used javascript for browser based security, JQuery form mask for guiding and formatting user input (and in some cases, restricting). Form Validator was a server-based security strategy that was extremely effective.

Since then, we have switched to HTML5 for the  […more]

Emails are a target for hackers. The single largest target is forms.

So many website process their user submitted forms with simple PHP code that uses PHP's Mail() function to get the data to their inbox.

I'll join all the other email transport developers in making it as clear as possible: PHP Mail() is seriously flawed and extremely difficult to work with. It's not that complex,  […more]

On two recent separate occasions, I have sent out files to fix issues.

It was well-meaning, trying to get a quick fix to a reasonably small issue.

I've been writing code and providing support for nearly 40 years. I know better ... you can't interrupt the development flow to send out a quick one-off of a software. There are so many problems with this  […more]
