JavaMail API dropping attachments

[John P]

Hello,

I'm building email messages and attachments via the JavaMail API,
which are then sent via sendmail. The attachments are mime attachments
of type "application/octet-stream". They are received via fine via
lotus notes and outlook, but in outlook express, yahoo, and hotmail
the attachment does not appear. Yahoo will even report the correct
message size. Any ideas on what the issue could be?

Any help would be greatly appreciated
