I've been helped so much by StackOverflow, so wanted to post this to save others the hours I spent debugging it:
I'm using a Java application to retrieve mail via IMAP/SSL. Fine for months. Now problems with a specific message from Yahoo. The message is multipart/alternative with a base64-encoded text/plain part and a base64-encoded text/html part.
Retrieval fails with:
IOException: com.sun.mail.util.DecodingException: BASE64Decoder: Error in encoded stream: needed 4 valid base64 characters but only got 3 before EOF, the 10 most recent characters were: "IPONREPLY>" :[com.sun.mail.util.BASE64DecoderStream.decode(BASE64DecoderStream.java:256), com.sun.mail.util.BASE64DecoderStream.read(BASE64DecoderStream.java:110)...
The content itself looks normal using Yahoo's webmail client. Looking at what is retrieve by my application in the HTML part, I see at the end of the base64-encoded text/html part:

</XHTML-STRIPONREPLY>
This is text that Yahoo recently started adding to messages. It works with text that is not encoded or uses quoted-printable encoding, but breaks base64-encoded parts.
I filed a report with Yahoo, so hope they will fix this soon.
