(See the EagleFiler online manual for full details.)

Emailchemy is a cross-platform app from Weird Kid Software LLC for converting email files from most popular email applications (including AOL, Apple Mail, Entourage, Eudora, Outlook and more) to standard, portable formats, including RFC-822 mailboxes, Thunderbird folders, Entourage archives, Apple’s Mail.app and more, for conversion and archiving. Features include a built-in IMAP server, de-duplication, and “utilities for splitting, sorting and merging email archives, and harvesting email addresses from email archives.”
Emailchemy 14.3.12 is priced starting at $29.95 (single license) for OS X 10.7 and up, Linux, and Windows. Updates require a renewal purchase after one year. A demo version lets you try the conversion process before purchase. The latest versions has full compatibility with macOS 10.15 Catalina.
Mail Archiver X is a Mac app from Moth Software Mainz (Beatrix Willius) for collecting and archiving into a database email from popular email apps – Entourage, Outlook, Eudora, Apple Mail, Powermail, Postbox, Thunderbird – and it can also import standard mbox files or collect email directly from Gmail, Office 365 Exchange or iCloud. Archived email can be exported in mbox format or to PDF, Evernote, text, FileMaker or SQL formats. Other features include a built-in email viewer, a scheduler, and a template for using FileMaker instead of the internal database, if you prefer.
Mail Archiver X 5.1.6 (or 5.2.0beta1) is priced at $44.95 for OS X 10.11 and up with a 10-day trial period. (Older versions are available with support for earlier Macs.) Multi-computer and multi-user licenses are more expensive. The latest version includes performance and user interface improvements.
Eudora Mailbox Cleaner is an old PowerPC Mac app from Andreas Amann that has the unique ability to clean up Eudora email archives.
Trying to migrate my old messages from Eudora to Apple Mail, I noticed that most of the information got lost or mangled in the process (all messages show up as unread, attachments get lost, non-ASCII character show up incorrect, HTML messages display as code instead of formatted text, …). Since I was not satisfied with this partial import, I wrote ‘Eudora Mailbox Cleaner’ which corrects all these issues. I later realized that problems are more widespread and added additional features to the application in order to support more email clients.
Eudora Mailbox Cleaner 4.9 is a free download for Mac OS X 10.2 through 10.6 only.
The new Thunderbird 68.4.1 release brings an important security fix with “targeted attacks in the wild abusing this flaw”, but “these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts.”
Thunderbird is Mozilla Corp.’s open-source, cross-platform email, chat, calendar, contacts and newsfeed (RSS) program, which features reliable email processing, smart folders, phishing protection and spam tools, special support for large-file transfers, quick filtering, Web searching, and plug-ins/add-ons for customization. See Thunderbird help topics for more information.
Thunderbird 68.4.1 is a free download for OS X 10.9 and up, as well as Linux and Windows. (Pre-release test versions are also available.)
