Simce pegasus is dead for the forseeable future for anyone using Microsoft email I need to move all of the emails to outlook. I came across this 15 year old thread talking about using mercury and IMAP to move pegasus folders to outlook. Never used mercury before. Anyone have any idea if this method would still work? Thx

Being a Kiwi myself, I thought, Pegasus might be worth a try.
However, I got stuck with the address book. The mail provider I am using for years supports CardDAV (only) as a protocol. Is there any change to synchronize Pegasus Mail with the address book on the mail server? Grateful for every hint in this direction, as for me it will be absolutely essential to work with that remote address book!

Thought look at discussion board as not been on for while. Found this and also thought worth a try. I had removed older Pegasus and was stuck with Gmail. The newer version as title above ran well and smoothly. The one click to set up with Gmail worked too, no issues. All mails downloaded and and the familier folders are so welcome. This is a very impressive feat and well done to making this work. I can imagine how tough in dealing with Gmail obstacles. Thank you David Harris for this and making it freely available.
I did setup my account and looks like am stuck with name of admin? Setup other users no problem.
Great work.


Are you searching for a solution to convert your Pegasus Mails, then you should try DRS Pegasus Mail Converter. I've recently used it and found it very useful for Pegasus Mail conversion. It can easily backup PMM, CNM, and other Pegasus File extensions into various file formats like PST, PDF, MBOX, EML, etc. You can also customize the name of the resultant folder using this software. This tool maintains the data integrity of the file and keeps your data safe. You can convert Pegasus Mails in bulk which saves your time and effort. It is compatible with all versions of Windows. Do check it out for a smooth and secure backup of Pegasus Mails.

On Windows 10. Have been using Pegasus for many years. Currently on 4.73. I have always used PMail with -Roam switch on a portable external drive, and it has always worked fine. The Sendto uitility is selected as the default mail app and that has always worked fine. However, I am now getting an error when trying to mailto from a website: "Can't communicate with Pegasus." Appreciate any help.

My messages to other peoples' addresses have started being bounced, and the fix I need is to set up my SMTP server use properly. I've got it to work in another (lesser) email client, but I've struggled with configuring Pegasus Mail.

It's not my SMTP server. The settings specified by the email provider are
Security - SSL
Outgoing Port - 465 or 587
Authentication - Password

I've tried various combinations of direct SSL or STARTTLS, port 465 or port 587. Haven't found one which works yet.

Here's the trace showing the SMTP transaction for direct SSL, port 465. What do I need to adjust?

When I delete messages, I get the response that the file is overfull (up to 2 gigs apparently).... and nothing more can be copied/saved into it. Apparently the deleted file should be compressed to save space, that's what the message says.... Why can't the deleted file simply be emptied completely??
I have no idea about this, being a very naive user (have used Pegasus mail for years but have no idea how it works, sorry..).
Can anyone explain the problem to me in simple terms, and how to resolve it?
Or should I just take my device to a local geek and get him to fix it..?
Thanks for any advice...

Please help if you can. I have an issue with Gmail and only with some emails with attachments. I can only log in through webmail, find and delete the "bad" email and then its working again.

Edit 05.02.24: after trying to download the same email from different server, I have the same error...

Pmail runs on win10 and updated to latest Version 4.81.1154

I wish to apologize for not getting back to all to let everyone know I'm back together as one of the other community members did a remote access to my computer and corrected problems for which I am extremely grateful.It seems this was the only way to solve the problem at hand and was very beneficial because as I feel it is so much better to look and see the problem than trying to read the many ways to fix.

Anyway I feel good and releaved the problem(s) have been solved and I'm back

Many thanks to all that tried to help


I'm really interested to know what David Harris' source of the news that Microsoft is phasing out support for Win32 applications is, since nobody else seems to know anything about it. It's true that Windows 11 and beyond will not have a 32 bit VERSION, and that free support for Windows 10 (which is available in both a 32 and 64 bit version) is ending in October 2025 (not "this year." ) But the 64 bit VERSION of Win 11 runs both 64 bit and 32 bit APPLICATIONS just fine and I've heard nothing from anyone else about any plans to change that.

Mr. Harris has been saying 32 bit applications are going away for years and that worries me.

Hi Everyone!

First-timer here so please pardon me if i miss any expected etiquette requirements smile

Currently, for emails that Pegasus Mail sends out, i noticed the raw headers of the received email has the field "X-mailer" which shows that the sender is using Pegasus Mail and the software version number.

In the interest of security and confidentiality, is there any way to remove or at least modify the abovementioned X-mailer field so anyone who intercepts the email in transit will not be able to see what the sender's email client software and/or version number is?

Modifying the pmail.ini file doesn't work, so hoping to find the answer here. Thanks in advance for any pointers you can give!

Pegasus generally works fine for most messages. But some messages, typically from institutions, start off with pages of text relating to formatting such as margins, fonts, etc. After scrolling down I eventually find the message. I just updated to version 4.8 but find the same problem. This is on my desktop computer which is running Windows 7. If I view the same message on my laptop which runs Windows 10 but Pegasus is set up the same way, the problem disappears. How can I get rid of the garbage with these emails?

I receive emails ok but get this message when I send:
11:22:09.863: >> 550 5.1.0 sender rejected. The email address you are sending as must match the email address you used to auth. Please check your SMTP settings. AUP#Out-1500

This problem started late last year.

My setup looks fine.
I talked to Spectrum Support and since I can send and receive email via spectrum webmail they say its pmail problem.
The header looks like this:

Hello - I have a number of users with a huge amount of folders.
There is a problem with a few...I can use mbxmaint to repair but I'd really like to be able to quickly see what the 'long name' of the folder is cross referencing with it's 'filename' I need to be able to identify FOL02D7F.PMM for example in Pegasus without going through each folder & checking 'Folder info'
I'm sure I'm missing something simple!

Hi all,
I have a issue with IERenderer (even as of current
when pasting formatted text (maybe a headline from a PDF or something similiar), an additional NEWLINE is added to the pasted text:

hello world.


"Paste special..." with unformatted text works fine.

any clues?


hard to find the right category for IERenderer.
Hopefully I'm not totally wrong here ;-)
