Maybe I am paranoid, but, I have been getting a LOT of these types of messages in my mail log of late. I have firewalled the biggest offender, who has made over 700 of these connects in the last day. I found my system loaded, and LOTS of sendmail prcessess running when I came in this morning. A tail -f of the maillog revealed all these NOQUEUE Null connections being made every few seconds. Could someone please shed some light on what is ( or might ) be going on here? Thanks in advance.
