must be decoded as

Technically, the way that OpenPOP handles decoding this series of encoded-word tokens is correct according to the spec, but unfortunately many mail clients incorrectly break apart long encoded-words such that they need to be decoded after their payloads are combined.

For anyone suffering from this problem, I highly recommend my own libraries: MimeKit and MailKit.

Hope that helps.
