I had thing running fine and mail was routing to scalix as it should. Then I worked on some DNS problems, changed my SMARTHOST in sendmail.mc, rebuilt sendmail.cf and all seemed well. However, now incoming mail is staying in my local users queue instead of going to scalix as it was. I tried unding all the changes I'd made but this was no help. Any ideas what stupid thing I've done to cause this problem?
lsof -i:25 shows sendmail listing on port 25 for 127.0.0.1 and scalix listening on the same port for my NIC IP address.
