Happy 15th birthday to POP Peeper

August 20, 2016

It seems like just 15 years ago that I started working on a personal email notifier because… well, who remembers?  On August 23, 2001, I put v.1 on my home page, known as “Mortal Universe Software Entertainment” (MUSE) back then, hosted on whatever ISP I was using at the time.  A few months later, I submitted v1.0 to download.com — thinking it was finished — and moved onto other things.  About a month later, download.com published it and I started getting feedback.

One of the first requests I received was to support Hotmail (it really was called “Hotmail” back then).  I thought it was an interesting idea.  In hindsight, it was one of the best and worst decisions… 🙂

The oldest version of POP Peeper I could find in my archives was v2.3.1, released May 21, 2004.  There have been some changes since then, but it’s easy to see that the interface hasn’t changed too much in 11+ years.  I don’t think that there was even a menu in the first versions.  Here’s a screenshot of v2.3.1 running on Windows 10:

But enough nostalgia!  For those interested in the programs of today — to celebrate POP Peeper’s 15th birthday, there’s a 15% store-wide discount this week, through August 27, 2016:



POP Peeper “DPI fixes” fixes

July 12, 2016

In POP Peeper v4.2, POP Peeper became “dpi aware” for the purpose of making text more clear in recent OS’s (Windows 8.1 & 10).  The side effect of this, which most affected people with very high DPI (> 150%), is that it made graphical elements very small, such as the toolbars.

The next version of POP Peeper will not only address the concerns with the size of the graphics, but will correct some other related issues, as well.  For example, you will be able to right-click on the header of the message list (and account list) and select, “Use optimal column sizes” which will take into account not only your DPI but also your current font.  You will also be prompted to auto-resize the columns when you change the font.

Since the graphics would need to scale based on the DPI, there are some new graphics, primarily for the icons in the message list.  When new graphics were used, a similar design and color scheme were used to keep it consistent with previous versions of POP Peeper.

I am particularly looking for people with high-resolution/DPI monitors to test this, so if you’re interested, let me know.

Below are 2 screenshots from Windows 10.  The first uses 125% DPI and the second uses 200% DPI.

POP Peeper v4.2: OAuth2 for Yahoo and Outlook

June 15, 2016

Last week, one of my Yahoo accounts which I semi-regularly check via IMAP started returning a login error.  After some investigation, I discovered that the account had disabled Allow apps that use less secure sign in, but not all my accounts have been affected.  So, after getting the appropriate access from the Yahoo Mail and Yahoo Developer Network teams (thanks guys!), I was quickly able to include OAuth2 support for Yahoo IMAP/SMTP.  And I threw Outlook support in, too, as they may decide to disable “less secure apps” in the future; however, it should be noted that, at this time, I could not find an option to disable/enable “less secure apps” in my Outlook accounts.

POP Peeper v4.2 beta 3 is now available, which includes the updated OAuth2 support for Yahoo and Outlook:
