Technically, there is nothing syntactically incorrect with the MIME message generated by Eudora. Unfortunately, Eudora 5.1 and earlier generates MIME boundary strings which can contain other boundaries as substrings.
There is wording in RFC 2046 (which wasn't present in RFC 1521) which states that such boundaries should be treated as the same. This is what Cyrus does.
UW IMAP whose original MIME parsing code predates RFC 2046, still follows the RFC 1521 text which mentions nothing about the substring case.
None of us know why the substring text was added in RFC 2046, but both Cyrus and UW can claim that they are correct. The fact that Eudora has been changed in v5.2 to match RFC 2046 is a good thing, and all users are urged to upgrade.
In lieu of this, I have just added a "eudora_mime_hack" option to Cyrus, which will be available in v2.1.14 ("real soon now") to work around the MIME boundary issue.

OK, but why does wu imap server works ? Can we expect cyrus server to correct this client issue ?
We can't tell all Eudora senders to change their habits and/or migrate to Mulberry, Outlook...
