TLDR: Folder window is messed up after a computer crash, a filling tray is gone, and all folders are in the "main branch", the folder for search results is also missing. What can I do?

I have my copy of Pegasus Mail set up with the Folders window always open, in what I think is called List view (i.e. not Preview). The folder tree has been the same for a very long time, though at times we perhaps add some message folders (to be used with filters), and perhaps also, as I had done, one or several filling trays.

That is, I had the standard message folders and some (but not all, I think, since it now looks completely different post-crash) of the added message folders were organised in a filling tray, say called Miscellaneous.

It looked something like this:
New mail
[Here probably was the system Search folder.]
[Any mail deleted during the session would be here; if none the folder's usually not in the list]
Diverse/Misc. [Filling tray]
--Several message folders (probably 15-18 )
Junk or suspicious mail
Main folder

And between the "system folders" were probably as mentioned a couple of the message folders that I hadn't moved, years ago, to the filling tray. I think I know which ones.

But when I started PM post a computer crash, has happened before but not with this result in Pegasus Mail, all folders were in alphabetical order, the filling tray gone, and so was the special folder for search results (wasn't in use at this time).


For a split second I first thought I had somehow moved one or two message folders from the filling tray to the "main branch", but realised that they all were there, the filling tray missing, and so was the search folder.

I guess I could simply add a new filling tray, move most of the message folders into it, and be done with it, but I want to know if this can be fixed in some other, proper, way, and what to do with the missing search folder (or will it re-appear if I do a search) etc?

I have been using Pegasus for about 25 years. It seems that I have this problem every time I get a new computer. I just moved to windows 11 and have loaded ver. 4.80. I run the setup wizard and enter all the same data as before; pop3, user name, email address, password, etc. Here is what I have entered for pop3:


I continually get a message stating username or password is invalid.

Any suggestions?

One of my Pmail files has a recurring problem with one folder: "Data error encountered 6629d7b00cb1a

re-indexing doesn't help and if the error recurs too often (as in a search that references this folder often) Pegasus crashes. There are several hundred messages with data I need to keep -- suggestions welcome!

I use networksolutions for my email server and they have been going through some gnarly security upgrades recently.

Last week I had to change the send and receive ports after Pegasus stopped working. I entered the new port into and got it working, finally.

Today Pegasus stopped sending and no matter what ports I try on one computer or another, I get the same error using port 465:

Peer connect failure.

Port 587 gives me this error:

error:1408F10BsmileSL routines:ssl3_get_record:wrong version number


535 authentication failed (#5.7.1)

This happened during the afternoon to both computers. I have only tried to adjust the setting on one computer knowing full-well that the other was working too until they both went down. Both are receiving. They are both simply not sending.

I'm at a loss at this point. I tried all the setting combination and nothing works.

Inbox emails disappeared. When using Pegasus 4.8 the emails in the Inbox were sorted alphabetically to be moved to their appropriate message folder. While moving an email to a message folder all of the emails from "A" to "L" disappeared. I have made a review (not hard) of all the Filing Trays and Message Folder and could not find the email which disappeared. I do not believe they have been permanently deleted, but if they have I need to know why it happened, so it does not happen again...

Hi all

I have been using v4.71 happily on Windows 10 for some time. Since a few days ago, every time I press the "Move" button to move a message from the "New Mail Folder" into a specific folder, PegasusMail freezes.

Task Manager doesn't show any problem (not "Not Responding"smile but the only way to unfreeze is to "End Task" and reload.

The move presets 1-6 work without a problem. The freezing problem is just when using the Move button.

Upgrading to v4.80 hasn't solved the problem. Though I haven't tried a fresh installation, as I suspect this has to be done in a strict manner.

Windows version notes attached.

Any advice appreciated.

System: Windows 7 (x64)

I had been using PMAIL v8.0 since updating from v4.73 back in March 2022. Then in June 2022 I set-up a Gmail 2 stage app password, which has been working fine ever since for accessing my Gmail account for POP, SMTP, and IMAP.

I have been patiently waiting for over a year now for either a patch for the v8.0 Dictionary problem to be issued, or a final version of PMAIL v8.1. As neither of those seems likely anymore, I yesterday updated PMAIL to the newest v8.1 beta that David released on Jan 10, 2023. It appears to be working fine.

3 Questions:
1) Is there any advantage in changing from using my Gmail app password set-up to OAuth 2.0?
2) Are there any disadvantages?
3) Should I just wait for OAuth 2.1?

Finally: if I do decide to update PMAIL v8.1 to OAuth 2.0, how is that done?

Thanks in advance for any and all replies.

Good Morning Group:

As I was shutting down the computer last evening, I noticed that one of my "MASDA" folders was now empty. I'm at a loss as to how this might have happened.

The folder in question contained an assortment of important information, including receipts, invoices, and important dates and times, etc.

Hopefully, the mind trust of this group can point me in the right direction to restore the folder's contents.

I look forward to any comments.

Thank You

Tom G, Sr.

My hard drive crashed and I have recovered the data to a new drive but I am moving it to a new computer. I had PMail v 4.73...installed and want to update to 4.80. When I installed it on the new computer, it gave me an option to set up or create something and I believe I unchecked that because I was planning to copy over my MAIL folder to the new PMAIL folder on C. When I did that, it said it recognized a new version, but none of my folders or emails show up. I installed all of PMAIL but don't want to try again for fear of messing up my husband's pristine new computer.

I saw a question from last year about moving to a new computer, but they had the same version on both. Below is the About/Info that was requested there.

Thanks in advance!

I have re-installed PMail v. 4.8 and starting over. I cannot send because a 530 Authentication is required. Explain to me what this is and how to do it or fix it. I am able to connect to GMail and receive but not send.

Computer crashed and had to reinstall Pegasus Email. Can receive emails OK, but cannot send. All attempts generate the following error:
454 4.7.1 : Relay access denied.

How can I reset my Pmail parameters to prevent this?

Please reply to if possible. Thanks.

PMail v4.8 on my Windows 10 has totally locked up. The start screen hangs and program does not respond. I think I need to uninstall and re-install. Can this be done without loosing my address books and contacts?

About 2 weeks ago my Office 365 OWA login unexpectedly changed its logged-in Timeout - and MFA insisted on a smartphone app. The Pegasus SMTP connection was rejected as invalid login details.

The first problem was eventually solved by me setting up Legacy MFA again and asking for new text MFA details at login. The process for getting an SMTP authentication code seems to have become a rabbit hole of jargon covering a multitude of potential administration requirements. Catch-22 and brickwalls everywhere. Including suggesting SMTP client API has changed to require Graph?? The Pegasus application registration had disappeared. Now sort of recreated but is not appearing in my users so it can be assigned.

I note that there are also warnings that MS will close the Azure AD service in September. My suspicion is that my account was transitioned to the new service without my knowledge or possibly even the ISP help desk's. Anyone any ideas?

I recently was forced to install Pegasus on a new machine, following which I set Pegasus up as the default mailto app. This, however, has triggered a hard block by my security program, PCMatic, who have marked the wsendto file as BAD. I then contacted PCMatic, who cheerfully told me to forward a copy of the wsendto to them for their verification and addition to their database of good files. I set about doing this, (using Pegasus), attached a copy of the wsendto file, and sent it off, only to get a rejection of the message:

Delivery has failed on the enclosed message for the following
reasons reported either by the mail delivery system on the mail
relay host or by the local TCP/IP transport module:

554 5.7.0 Reject, id=07340-05 - BANNED:

I think it highly unlikely that there is in fact the slightest issue with the sendto file itself, but there seem to be an awful lot of agents out there who disagree. Any advice on how best to resolve this? (Erase and re-install Pegasus, to get a clean copy of the wsendto file, in case my copy really has been altered by some evil actor? Go after my mail provider? What else??)
