Embedded images on email

Jul 28th, 2009

Hi.

I have a problem when trying to embed pictures to an email. It works fine on windows server and the email is shown correct but when I try to put it in production which runs on Linux (mono 2.4) it sends the pictures as attachments (and deletes the first one of them.). I have tried alot and have searched everywhere but with no luck.

The code below works fine in windows but attach the embedded pictures in mono. Any surgestions what I can try, I'm running out of idears.
