error Handling Threads

[jpbarreraa]

My app sends emails throughout the day. I use the thread id parameter and I can get that the sender of the email is seeing all emails in the same thread, but the recipents of the emails are seeng each email as a different thread. I tried to work around it on my own, but i think that the package is not adapted to do so and my recipents are full of spam. Does someone have any idea or suggestion?
