MailMessage and Message Queue

Question

Hi, Does anyone know how to serialize a MailMessage object to a Private Message Queue? I am trying to create (mail) message objects and save them to a queue so that another process may pick them up and send them through the SMTP server at a later date. The process of creating the emails is quite lengthy. I have 1 process wrapping up the emails (slow) and another to send them out (quite quick). This way, if the SMTP server is down, the process of creating the emails is not held up. I would be open to any suggestions on other approaches to my probelm. Thanking you in advance K
