Hi I have noticed a strange trend in some of my servers mail logfiles.
The phenomina consistes of 29 (exactly and every time) emails addressed to (nonexsistent) 29 different usernames. Since i hardly have users on my system, these emails get bounced. The sender is allways different, but the 29 email names never repeate, suggesting to me a distributed email-guessing attempt directed from a centeral name-list anf performed by different end-users 29 names at a time. So my question is: Is this something new, do any other sysadmins see this ? and if it is not new, then what is it, and how to guard against it ??
