Hello - got one user who I think has been mucking about with Pegasus window sizing & now we can't see the preview pane for highlighted messages - is there an ini file or something similar I can configure to default?
Thanks for reading!

Dear friends,
Since today I can not create a message containing an image which I import from


The 'ready to send' message contains a rectangle of the image size and in top left corner with a red question mark. Hovering over this I see the message "Error 120006 The URL does not use a recognised protocol".
The message is compoled with Rich Text.
The relevant part in the HTML facet reads:

<div align="left" style="min-height: 594pt; "><img src="cid:2209265.1683533827.31039" width="754" height="792" border="0" alt="graphic"/></div>

I do not see where the problem may come from.

We use Pegasus 4.80 over a network, several users, nothing that complicated IMHO, although we have been using Pegasus a long time now... Server and clients are mostly Win 10 Pro.

Since updating to 4.80, there have been a very few emails where, if you click on Reply or Forward, Pegasus instantly crashes. Bounces however are no problem.

I've tried the same from several user's accounts and devices, and get the same result, so it's not likely to be an OS issue.

Is it attachments? Some of the emails have attachments, but not all.

Is it the addressee? No, we can email them ordinarily, and even reply to other emails, so it appears to be something that only occurs when the specific odd email is replied to.

In the headers of the emails, I can see some common factors that indicate the sender uses Office365/Outlook, perhaps in conjunction with Exchange. No idea if these are relevant or interesting, but I'll share some if someone thinks it might help.

Finally, the crash usually produces a couple of entries in Event Viewer:

Any thoughts/ideas?


In the last week or so, I can no longer send emails with Pegasus Mail. Receiving emails still works. Here's the error:

14:38:08.653: >> 250-AUTH CRAM-MD5 LOGIN PLAIN
14:38:08.653: >> 250-STARTTLS

14:38:08.737: << ...gobbledygook...
14:38:08.775: >> 535 5.7.0 authentication failed

I phoned the email provider, but they were no help. I can send via their web app. I updated from v4.7 to v4.81, but that didn't help.



When I try to connect, it fails with:

"The IMAP server that manages this mailbox or folder has reported an error during the operation you have attempted to perform.
The operation cannot be completed."

I've tried various combinations of the security settings.

I've set the System message reporting level to "5 - Debugging messages" but there's no more useful info in the System Messages window.

How best to go about troubleshooting this?

I have been a user of Pegasus since...(the dark ages, or rather when the InterNet was still free, and uncensored, unlike now). I had to stop using it, for some reason that I've long forgotten. It is a competent, well designed, functional e-mail program. It is a great program, thanks to David Harris. I'm surprised to learn that Herr Harris is still supporting Pegasus...thanks.

However, I've been using ProtonMail, their email client stinks. I've expended most of today trying to cause Pegasus to work with ProtonMail...but they don't support standard IMAP or SMTP, other than through something they name Proton Bridge, which only works with OutLook, and ThunderTurd and something else?

I haven't been able to cause Pegasus to work with ProtonMail. My end-goal is to be able to alia my email and send and receive via my non-profit .org domain name website, which in the past with a different email provider was extremely easy to do in Pegasus.

So here's the question, does anyone know of any VPN email provider that works with Pegasus Mail?

Any help is appreciated.

Is 4.81 stable enough for everyday use? (I really miss the spell check!!!)

Any idea when the official v4.81 might be released?

If I decide to go with this one, does it just install right over v4.80 or does v4.81 Beta come with installation instructions?


recent by philherz  ·  Apr 26 '23 at 3:35 pm

Using v4.80

I haven't changed anything and I can still access my email using a browser, but for the last 2 days I can't download any of the new emails. I've closed and reopened Pegasus and rebooted my computer without luck.

Is there one corrupted email that is causing this?


I get this login script:

This morning I noticed that the Pegasus window was gone. I restarted the program, and rebooted the computer but nothing changed.

What happens is this: When I double-click on the Pegasus shortcut, the start-up window appears, but when it closes, the main window is not visible. Clicking on the icon at the bottom of the screen does not make it visible. However, the program must be working somewhere in the background, because i can hear "new mail messages" when I send test mail. Also, I can right-click on the icon in the notification area and get a "new message window"; however, I cannot do anything with it, except closing it (no clicks accepted; no keyboard events processed).

I guess something happened in the OS (Windows 10) that got Pegasus to store a faulty window state, but I do not where or what. Anyone have a clue?

I still think I am using some kind of hybrid of Pegasus; I installed 4.80 some months ago, but immediately had a nasty crash pasting something when composing a message. I then downgraded back to 4.73, but still had some problems with pasting in new messages, so I assume a part of 4.80 did survive the downgrade. For my problem in January, I assumed this information was not relevant (a correct assumption, it turned out), but this time I am not so sure.

I have been using pmail for 20+ years, and it has always faithfully recorded my sent mail. Two days ago it suddenly stopped doing so. I checked in the "messages and replies" setup, and the "copy to self" switch is still set to "On". I wondered whether it had stopped because the folder had grown too big, so went back and deleted a whole raft of old messages. Still doesn't work. What next? (And, warning, I am an old man, with simple computer skills.)

I hope somebody can help me with the following:
Step 1. I send in Pegasus an email to myself
Step 2. I open the received email and press the "reply" button
Problem: The "to" field stays empty.

Extra tests done:
a) If I open the email in another email program and click the "reply" it seems to be filled correctly.
b) When I open an email somebody else sent me, I got a filled "To"-field.
c) When I send an email to myself not using Pegasus but another email program, and I try to reply via Pegasus Mail it gives an emtpy To field.

(I'm using Pegasus mail v4.80 for windows, build 1028 )

Any ideas how to fix this?

First of all, I accidentally posted the following under the Mercury software discussion. If an admin see that, please delete it.

Hello: I have been a staunch user of Pegasus for so long I cannot remember my first use of it. I regard Pegasus as the very best e-mail client I have ever used. Also, many of the members of my family use it.

I heartily thank David Harris for building and supporting such a magnificent piece of software.

Now, my question to the group is how do I get Pegasus to run successfully under WINE in a FreeBSD environment?

But, for now, forget the FreeBSD part. If I can get it to run under WINE, I believe it will run under any Unix-like system.

I know that one must work-around IErenderer, and at this point I am unsure how to do that. I DO know that others have been successful at this, but I have been unable to learn how they did it.

I believe I have successfully installed WINE on my system, although I still need some tutoring on how to use it.

In any case, although everything associated with Pegasus and WINE "appears" to be correct, when I attempt to start Pegasus, the system "messes around" for several seconds (proved by a clock icon appearing), but then quietly just quits with nothing showing on the desktop.

What I am trying to do is to build a Unix-like system to replace all our Windoze installations. So far, I have accomplished some very good things, and it is looking like I will eventually have what I need. But this issue with Pegasus has been a BIG problem for me.

Hello, I've been a pmail user for years, I'm not a programer so I'll try to describe my problem as best I can:

I've always accepted pmail as a text based email client but it's becoming harder to use because many mail messages now have embedded HTML content. Sometimes I can save the message as .HTML and Firefox will open and render it although in the past I've tried linking to the firefox .exe and pmail doesn't seem to always want to go there?. I've noticed many messages being sent now seem to be intended for mobile devices when I use a PC. I've coped with these inconveniences and saw v4.8 had been released with HTML rendering changes so I updated from 4.71.

Now my problems seem to have worsened. Consistently when receiving Ebays 'We got your order' confirmation and airline booking confirmations full of html code and links to their promotions.

Before, I saw code in messsage view and could work out main message content in Raw View. Now on 4.8 I see a blank message screen and if I try to do anything, I get the Windows 7_64 message: Win PM-32 Floating Point division by zero error. There's no Windows event app crash error logged, but that doesn't inspire me as a stable situation.

For now I'm reverting back to 4.7 because even though it doesn't render HTML content the apps don't give error messages.

I have been using Pegasus mail for many years, since at least 1996. I have moved my email from one ISP to another many times. I recently had a HD crash and have decided to reinstall Pegasus to a different location after my crash. During this process, all my mail is working just fine but I have discovered that my Help system is not. Since I don't access the help system frequently, I am not sure if it was working prior to my crash. I am using W10.

I have read the thread from Tom Barkas from 1/31/23 and still cannot get things working. The weird thing is that if I launch Pegasus from an old mailbox, the help system functions properly. But if I launch it from my currently used mailbox, it does not.

I have confirmed that if I drag winpm-32.phc onto showhelp.exe, it launches the help system. This is visible in Task Manager. However, if I try to invoke the help system from within my current mailbox, nothing happens. An entry is created in Task Manager but it contains no data on the line. Where the data should be is completely blank.

I am attaching the info screens from both mailboxes. "oliveral" (help works) is the old mailbox and "indynet" (help does not work) is the current mailbox. Besides comparing the info screens, I have also examined the PMAIL.INI files from both mailboxes. The old oliveral INI file contains some references to non existant directories. There are references to C:\PROGRAM FILES\PMAIL\MAIL\oliveral. I believe that was the recommended location for files many years ago. But I don't see how that would cause the help system to work.
