Hi people, I am having difficults in my exchange server to send e-mails. Sometime its stop to send external email. No event log. To enable send email again, I change my connector, changing the IP address to name server (FQDN). After that its stop again and I repeat this step. I already tried to recreate the connectors but didn't work. Someone have an idea what is happening? My exchange struture is: 1 Front-end server, 2 back-end server in cluster. All Exchange 2003 Thanks.

You can set diagnostic logging for SMTP to maximum and it will generate more events to review. How are the connectors configured? Do they use DNS or forward to a smart host?
