Change default exim sending email (from)

Hi,



We use a server under NAT and it hosts a domain with unvalid tld as "MI" and when we try to send a mail with phpmail at most cases we got this error in /var/log/exim/mainlog

So how I can change default sending email because these emails are automatically sended from our ticket systems when we reply to our customer tickets and this is a problem for us?
