If I feel particularly motivated sometime, I may try playing with the -f flag and see if that makes any difference on our system. Unfortunatly my web host was bought out recently and this happened somewhere around the time they moved the serves also. So, there are many variables.
In the meantime, I switched to using SMTP and it all seems to work fine now! I even got errors when I was using a server that didn't allow forwarding at first. Would have been nice if I got errors from sendmail when it failed. I now suspect that NO mail has gone out in about 3 weeks (sigh).
Anyway, I got the problem worked-around for now. Hope no one else is having this happen. Thanks.
