Blueseries resends mail

Submitted by Tobias L on Fri, 06/14/2013 - 10:46

Our Blueseries is connected to our exchange server, who relays. When sending mail from blueseries and delivery takes more than 30 seconds, Blueseries resends the mail. One mail can generate 5-8 resends. All copies of the mail is received by the recipient. Is there any way to make Blueseries not wait for the message to be delivered. Alternativly can I increase the timeout from 30 seconds?
