Lately I've been getting some error messages I'm not familiar with, and
was hoping someone here could help.
 
The examples below are from new subscribers to my list; most, but not
quite all, traffic to them seems to bounce. I also have subscribers at
another site that cause the same error, but that site only produces the
errors intermittently.
 
All the addresses are legit; no misspellings or anything like that.
Anyone know what the problem is, or how to fix?
 
Thanks,
Aaron
