I am actually replying to an email. This address is one that we send to every day and all of a sudden it stopped working. Further, I have never seen this type of error before...specifically " mail not terminated with '.'" Thanks for the response...

See http://www.networksorcery.com/enp/protocol/smtp.htm for more info as well. Are you seeing this to a specific domain, or to specific users, or just everywhere? Obviously you can send mail, so is there a common thread?
