Hi,  
I want to set the message-id of the messages sent using the mailer (so  
that  
I can recognise replies). Has anyone done this?

I’ve tried these in my mailer model:  
@headers[“message-id”] = “12345”  
#gets ignored  
and  
message\_id = “12345”  
#gets ignored  
and this separate bit of code:  
mail = MyMailer.create\_reminder\_message(user)  
mail.message\_id = "123  
MyMailer.deliver(mail)  
#there’s no deliver method on MyMailer

Any ideas?

thanks  
Thomas

This method should definitely work, I am using it with success. The  
deliver  
method is set up by action mailer, it is not a method you add to  
MyMailer  
yourself.

You might also consider using TMail.new\_message\_id to create a message  
id:

mail.message\_id = TMail.new\_message\_id
