We just had this happen again. Same MO: ramdom subject and message
body, no links or email addresses in the message, multiple incoming
relays, various recipients, Message-Id starting with "CHILKAT-MID".
Three compromised accounts have been used to send this "spam" starting
Sunday morning. I'm using the Message-Id to trap new accounts.
Coincidentally, we has a phish get through to a number of our users last
