back to article Finally: Historic Eudora email code goes open source

The source code to the Eudora email client is being released by the Computer History Museum, after five years of discussion with the IP owner, Qualcomm. The Mac software was well loved by early internet adopters and power users, with versions appearing for Palm, Newton and Windows. At one time, the brand was so synonymous with …

      Re: Keep it going

      Same here. I fondly recall Eudora, with all attachments in a separate directory in their original form. Made searching attachments very easy. Was I on Win98 at the time?

      I eventually was forced to move to Outlook, although I can't remember why. I found some software that converted all my Eudora email and folders into an Outlook PST file.

      Strange how one can be nostalgic for old tech.

        Yea, I forgot. That separate folder for attachments was definitely one feature Thunderbird should have adopted, but never did.

    No wonder it's such a horrible bloated old mess. I've dealt with many email clients in my day but rarely found one I disliked as much as Eudora (Windows 10 Mail app and virtually all mobile email apps excluded.)

        You're welcome to your opinion (I know other people who irrationally love Eudora without ever being able to give one point in its favour other than that they're used to the mess.)

        However... I have actually used Eudora myself and had to deal with it on other people's PCs now and then (within the past year, too), and it IS inevitably a horrible mess. Bloated is subjective and relative perhaps, there are undoubtedly even more bloated clients out there... but regardless, those piles of old libs that aren't otherwise on the system is Eudora induced bloat.

        Old is fine by me - I use loads of software that is ancient and great - but this was pretty horrible decades ago and hasn't improved any with age!

      I have a customer I support that uses Pegasus. They were Netware users and that was a compelling reason for that choice at the time, as Pegasus integrated with NDS, so hot-desking was a doddle.

      Pegasus is still a reliable alternative to Outlook. The user interface is traditional, there is no need for continual updates, and the scope for catching nasty infections appears to be less.

        Re: Pegasus

        The problem with PMail is its developers has been rewriting version 5 for years, and because he wants to do everything from scratch alone, he will never finish it. That's why the UI is "traditional", and there are no updates...

          With Pegasus mail + Netware, the security was soooo shitty that when I went to Uni we used to read the staff members personal email just for kicks. No real evil intent, all it required was an understanding of IPX programming and how Netware (& Pegasus) worked.

      Me thinks you are rather misinformed.

      There's a truly excellent and free (as in free of charge, no money or strings attached) e-mail client that's been out there since December 1989 when it sent it's first email.

      That's almost 30 years ...

      Yes 30 years.

      Find any other software that's been out there that long and it is still supported by it's author.

      See here:

      I'm talking about David Harris' Pegasus Mail e-mail client.

      I started using it many years ago when running MS software (and after trying out Eudora), very briefly under DOS and then from W3.11 to XP till I decided to leave MS software behind.

      I now use it with Wine in Linux.

      For a number of reasons explained in his site, it will not be ported to Linux or released as Open Source, but it has never let me down and even though I have looked at many other email clients, this is undoubtedly the one I'll keep using.

      Kudos to David Harris.


      1. Peter Gathercole Silver badge

        Re: Email is fundamental to modern life

        Whilst I respect David Harris's position regarding Linux, I suspect that if he is still working with Pegasus, he needs to at least update his blog regarding his position. It's dated April 2005.

        Reading it, I don't think he's really understood GPL and LGPL. Just producing a free package that runs on Linux does not necessarily mean that the package needs to be open-sourced or published under GPL, as long as it is written correctly. It is perfectly possible to produce binary only software for free distribution under another license, or even commercially, as long as you do not incorporate any GPL code in your code-base. Most of the required C and C++ libraries required to compile your own packages are published under LGPL, which allows them to be linked in either statically or dynamically to a binary package.

        This fact annoys some of the Open-Source stalwarts who want to convert the whole world to software that is free and open (RMS, I'm looking at you), but the licenses were written the way they were for a reason.

        I appreciate that if he uses an editor from a third party as part of the package, then he would have to get some agreement on that, but Linux repositories are full of editors, which provided they are run as separate processes, can be called quite freely from another program without any licensing issues. Using it as a widget may be a little more problematic, although much of, say, Qt or GTK+ are published under LGPL, so there will be editor widgets in them somewhere.

        The issue of support is only one of degree. At the time of writing the blog, he was doing it for Windows, so doing the same for Linux, once the learning curve has been followed, would not be significantly different, just more.

        But given the date on the blog, and the overall age of the software, I suspect that he is just not interested in porting the product, and if this is the case, when Microsoft starts removing some of the legacy APIs in Windows, the Windows package may be doomed in the log term.

        Opening it up to other developers is the only real way to keep the package alive over the longer term. And if Mercury is actually a functional email server, then a Linux port, even a commercial one, would be really welcome.

    Eudora Euphoria

    I remember the unbounded joy of getting my Palm Pilot to talk my Siemens phone using infra red and then downloading mail using Eudora. I was in a meeting with the High Paid Help a little while after and got a ticking off from one of the directors for playing with my Pilot. I told him I was taking notes and checking emails (both true). He didn't believe the bit about emails so I showed him (he had to shuffle round the table cos of the IR link) and he was amazed. A few weeks after this all the directors turned up with Blackberries, and I like to think that it all started with my Palm Pilot and Eudora

    Right before the turn of the century my email was, for all intents and purposes, "on" a floppy disk I carried around (as space on the server was at a premium), which contained the "data" folder for Eudora, which was installed on all available Windows 3.11 for Workgroup computers at the ISP I physically *visited* to read it (I didn't have a home internet connection then).

      By good, I mean it showed different mailboxes in different windows - instead of this really stupid modern idea that everything has to be in one window where you switch mailboxes from the menu on the left. The Eudora way is just so much easier to work with.

      14.4K on the Nokia Communicator up till 2004. Or twice as much billing per second for 28.8K. It wasn't the iPhone that made Mobile data possible for the masses, not directly. It was 3G (245K, which iPhone originally didn't have, it used GSM's EDGE) and cheap data packages instead of per second or per Megbyte expensive billing.

      The home landline was local call rate billing till 2006 and still only 33K then.

  15. WolfFan Silver badge

    I remember Eudora

    I also remember why I (reluctantly) moved away from it.

    1 Eudora had problems with IMAP. Eudora had _serious_ problems with IMAP. Around 2003 I started to set up new email accounts on IMAP servers; Eudora barfed, repeatedly, with several though not all of them. I could never figure out why some IMAP accounts worked perfectly but others emitted the magic smoke on contact. It was easier to just find a replacement email client.

    2 Eudora had problems with UTF-8. Eudora pretended to be able to handle UTF-8, but really couldn't. This broke some mail. In particular it broke some mail from people who we had to work with and who used UTF-8 because they had to talk to people who didn't use the Latin alphabet and it was too much like work to rig their system to use two different charactersets, so all outgoing mail from them was UTF-8. Eudora would usually handle the posts, but on several occasions it broke spectacularly. There was a plug-in which handled UTF-8; it broke, too. Once again, it was easier to just find a replacement email client.

    3 Qualcomm went off their meds. Instead of doing things like fixing the IMAP and UTF-8 problems, they did things like adding 'peppers' to tell users how 'hot' their posts were. My users started to compete to see how short they could make a post and still get three peppers, without using any profanity. The champ got three peppers with a post 11 words long and containing not even one 'objectionable' or 'inappropriate' word. Suggestive words, yes, but nothing actually profane. This 'feature' was amusing but useless. It was not the only such feature in Eudora, just the most spectacularly idiotic.

    4 Qualcomm went further off their meds. They had the 'free' version, which was limited; they had the 'supported' version, which displayed ads in the lower left corner... and which screamed bloody murder if anything covered up the ad display. At this time there was a useful add-on for Macs which displayed a list of running apps; the default location was right where Eudora had the ads. Users thought that the add-on was a lot more important than Eudora. There was the 'full' version, licensed rentboy fashion, for a year. We noticed that new versions of Eudora tended to show up at 13-15 month intervals, so that the license would have run out and we'd have to pay again. It was cheaper and simpler to get a replacement email client.

    5 Eudora supported encryption... if you were in the US. Export versions didn't have the encryption, and that remained so for some time after the Feds stopped saying that encryption software was a munition of war and requiring an arms dealer license to export it. On occasion our staff had to go outside of the US, with their laptops... and the munition of war installed on those laptops. We didn't feel like applying for an arms dealer license. We also didn't feel like installing the crippled export version. We particularly didn't feel like installing the crippled export version after the Feds (reluctantly) stopped saying that software was the equivalent of cruise missiles. Other people ignored the Feds. It was simpler to just get a replacement email client.

Everybody is so hung up on using web browsers for everything, the talent and resources to develop purpose-built clients are rapidly dwindling. Certainly the Thunderbirrd-next folks are so busy with their yak-shaving that the client is going to become unusable before they even decide what colour they're going to make the menu-bar.

    I worked at a US university where allegedly only Eudora was compatible with their mail server for some reason. On day one I found out that Thunderbird (or was it Seamonkey at the time?) worked equally well. The bonus of the Netscape replacement was it's UTF-8 friendliness, unlike Eudora's, which was important as half the lab used in their emails non-Latin languages. So I got hated by the IP admins, loved by some coworkers and generally had fun. But I still cannot understand why some people actually liked that software.

    Still use it

    After abandoning Demon's Turnpike for Windows I still use Eudora after nearly 15 years. It's lightning fast and besides, I still like to compose mail offline on my main PC. I can back it up instantly or reinstall it with drag and drop. I can just about forgive the UTF-8 charset bug that smashes up some emails but that's become an embarrassment. Worst thing is how many of my recipient's see shonky Times New Roman message bodies although I see eg Verdana. You used to be able to coax it into fetching Gmail once you patched the QCSSL.dll and it could sort of handle Live mail, but configuring secure sockets every day/ week made all that unrewarding. Gradually it is falling apart, bit by bit. I would be over the moon if it could be brought up to date as a modern offline Windows email client with none of the Outlook bloat.

    I really can't decide whether to stump up £1,000 over the rest of my career for Microsoft Office 365.

  24. jmcinatlanta


    For way over 20 years, I have been strongly into Genealogy research on my various lines, and I started at the very beginning with Eudora. I loved this program! It was so easy to use, make folders for each surname, correspond with hundreds of different people, and compose emails. I used it up until Comcast could no longer support it, and sadly I could never find another program like it on the market. I signed up with Outlook and didn't care for it, and I now am using Comcast's email, but don't like it. It's cumbersome and hangs up easily.

    I have never figured out (with such a big following) why the program was never updated and produced for those who would have stayed with it. You don't have to discontinue one program to move on to another.

    I would love to find a similar program such as Eudora that I could install onto my computer, that was not an internet based one. If there is one and I have just missed it, I would love to hear!

    Eudora Archiving

    Eudora has serious problems as an email client, but software that can send and receive email is trivial. The real trick is making sense of what you've received, and Eudora is still better than anything I've ever seen for archiving, filtering, and searching email. I'd pay a lot for a version that just imported and stored.eml files (or whatever) from a client, rendered them properly, and retained all the archival and customization features.

      I agree. I've been using the paid version of Eudora since Windows 95 days. Every time I change computers and Windows versions it still works. Last year when forced to change from XP to Windows 10, I thought my Eudora days were over, but I tried to install the old original Eudora exe file just to see what would happen. Worked like a charm.
