I don't know about that. If it was sendmail, fine because sendmail does 
provide mechanisms for multiple access to a mail in the queue which is 
how sendmail itself treats mails in the queue when you have multiple 
queue runners. I have not used exim so as far as I know, only sendmail 
actually tolerates a third-party touching mails in the queue.
