Bare Bones Email Program
Welcome to the home of Pegasus Mail, the Internet's longest-serving PC e-mail system, and of the Mercury Mail Transport System, our full-featured Internet Mail Server.Pegasus Mail is a free product, dedicated to serving all who need it, whilst Mercury is a modestly-priced commercial system that allows free use for private and non-profit users.
Now, installed on my machine, using IMAP to interact with 4 different email accounts (e.g. two personal Google accounts, one Google Workspace for Education, and one ProtonMail via ProtonBridge), Pegasus Mail takes up hardly any space.
Wondering how much? 45 megs.
Wow. One benefit is that you can copy the folder (PMAIL) from your C:\ root onto a USB drive, make a few edits, and voila, you now have a portable email program that is 45 megs in size and doesn't choke every time you run it (which Thunderbird would do, making it impractical even with the PortableApps version).
I have to admit it was a bit much to setup, but the Help files are detailed and easy to follow.
Update: Another email program I played with, that doesn't support HTML like Pegasus Mail, is Sylpheed. I've dabbled with Sylpheed before, so set up wasn't difficult. It only takes up 30 megs. But be aware that you won't be able to write rich text format messages or HTML. It's bare bones text.
Of course, for the purposes of this blog entry, that's not a bad thing.
