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
