You data on Pegasus Mail is outdated. Application is now on v4.41 which major improvement is a built-in bayesian spam filter.

Thanks! I have updated the version number and synopsis.

Pegasus Mail, a really excellent E-Mail-Client.
I am working with this for years, so everyone, give it a try :-)
There are also german and french versions available!

Pegasus is a very nice mailer. Version 4.41 supports a command-line option: "-ROAM" meant to support serverr-installs and USB-sticks. Look it up in the help-file.

There's a nice guide by Harri Nykanen at for WinXP SP2. I believe it can be easily adapted to XP SP1 and Windows 2000.

Other Pegasus Mail "must-view" websites are Han's Personal Site ( and Rob's Pmail Portal ( Enjoy both!

Pegasus Mail's support for Japanese seems to be quite poor. Also, development on it has stopped.

Euler 2007-07-11 15:39

Just saw this last statement today. You're somewhat wrong J44xm.
Pegasus Mail does support languages of different "alphabets", like Hebrew (LTR), Russian, Korean and Japanese (can't swear as I don't speak any of them), even in late versions. After adopting Unicode (among 26 other charsets) it extended its support much further.
Besides this charset thing, there's nothing out there that matches Pegasus Mail power and functionality. It's the One mailing system, not just a mailer.
And BTW, it's quite alive and well. New versions are on their way. See for yourself. ;^)

I find it very full free email client as long as you don't use IMAP. IMAP with Pegasus mail is way too slow.
Please DO correct me if I'am wrong, and also GUI glitches appeared from time to time.

Not entirely portable adds various keys to the registry. Search using 'Pegasus Mail' in regedit and you'll see.

v4.62 is available

v4.63 is out. The developer is working on v5, which is said to have improved IMAP support.

In development since 1990, still free and still going, this mail client absolutely needs to be in TPFC...

Version 4.7 is now out.

The supported versions of windows have changed. To quote from the website:

"Windows 98, NT, 2000, XP or Vista; we believe Windows 7 poses no problems, although we have not yet done extensive testing on that platform. Please note that Windows 95 is NOT supported."


Checker 2014-04-02 17:03

@ Craunch: Thanks ... and updated ;)

I've been a satisfied Pegasus Mail user for 15+ years.

Before Pegasus Mail didn't save sent attachments, has this changed?
