This app works with: Basilisk II,

The Mulberry email client was marketed by Cyrusoft from approximately 1995 to 2005. By late 2005, Cyrusoft International/ISAMET declared bankruptcy and went out of business. In August 2006 the original author, Cyrus Daboo, acquired the rights to the source code. Mulberry was then made a free software, and by 2007, Open Sourced.

Mulberry started off life as a software project that was really meant to help the author learn more about the internet and internet protocols used for email. However, it became much more than that and garnered support from a small (in internet terms) group of users and institutions many of whom relied on the product as their primary email tool.

Whilst it started as only an IMAP client and only on Mac OS, it has grown to cover not only other email protocols, but also calendaring and scheduling and is available on Mac OS X, Windows and Linux systems […]

Now Mulberry itself is free, though its future is still cloudy in terms of whether development will advance or not...

Excerpt: Mulberry "About Us - A Brief History".

For versions that are compatible with other Operating Systems: Visit the Mulberry website.

Architecture: 68k PPC x86 (Intel:Mac)

I've successfully used Mulberry v2.0.8 in Basilisk II (build 142) running Mac SSW 7.1.1. Not tested by myself in other emulators and Basilisk II compatibility is noted for this version of Mulberry and Basilisk II, only.

The development of Mulberry appears to have stalled, the final stable released version is still at v4.0.8 (2007).
Perhaps this page can help to draw some attention towards that project.

Hi MikeTomTom,

Thank you for your reply. The results from my limited efforts are that it seems doesn't have the actual SVN repository archived.

I have found some links to the source code of the "Fork from the v4.1d1 branch of the mulberry mail client" on GitHub, as follows:

First, this seems to be the first person to have put the source code up on GitHub:.

Here is the list of those who have made forks from that:

I haven't looked at all of the forks, but this one has a few commits that are as recent as 2017:

Hi robertson. Thank you for taking such an interest in this project and for all of the links.

Unfortunately I don't know the whereabouts of the source. The pre-OS X version was closed source and proprietary. I guess the only way to get it would be if Cyrus Daboo decides to release it. If he is at all contactable, this might also be an option.

I hope that the links will prove useful to you (in that they have archived the source and not just the links to it).

Does anyone know where to get the source code for this? (Having used it on Mac 9.2.2, I would love to see if this program's excellence carries over into the Linux realm. Alas, the Linux binary download from the Mulberry website is, none too surprisingly, not cooperating with my current Linux/amd64 setup.)

Sad to say, there are many broken links on I haven't tried to pull the source via SVN yet per the instructions at, but the state of and makes me think that I will have to try somehow to get it from the links.

(For those who like following clues, it looks like the source code of the Linux version might be found in the FreeBSD Ports tree as well: )

Also, is there any word on the availability of the source for any of the pre-Mac OS X versions of this?

In any event, thanks to all who have helped make this program available!

As of today (Aug. 22, 2018), I have 3.1.6a working with Microsoft's IMAP, POP, and SMTP are all working.

(I think and are identical to with respect to the mail servers.)

version 3.1.6a works with at least some IMAP servers w/SSL. I have not been able to get it to work with iCloud's email servers.

How does this compare to something like Eudora?

Couldn't say. I haven't used Eudora since my 68k Mac days and it was only the "lite" POP-mail version that I'd used at the time (I stopped using it when they introduced adware versions of Eudora). This version of Mulberry sends and receives IMAP mail from my Basilisk II set-up, running Mac SSW 7.1.1, so its worth it to me for that reason alone. However it'll run on a Mac II or newer Macintosh. It comes with a comprehensive user-guide (above link).
