Rick,
I got messages from you and karlp. I hope you got my response.
I'll have a closer look at the logs.
I am planning on migrating the server box to 7.2 and a 2.4 kernel. I just 
want to plan the migration process through as the server has been running 
fine until this sendmail snafu.
I have built custom kernels and upgraded kernels before. I just want to be 
careful not to break what's working :)
Here's a ?snipet of maillog slightly edited from 05/01/02 that hints at a DNS 
error.

Thanks,
Scott
