Hi Kevin -- No, no numbers. The message actually starts like so:

I don't know who or where postmaster@2031342 is. This behavior involves traffic from the usnwc.edu domain and seems to relate to a small attached XL file.
The behavior is new. Thanks for the links. I don't think I'm doing any of those bad things.

It could be related to the XL file you attempted to send. Typically, a postmaster error could be because the file type you tried to send through SMTP was rejected by the server. It's also possible that the recipient's email address rejected your correspondence, thinking it was spam. -Kevin M. Cox Support Forum Moderator
