Hello,
	The other day I noticed the following system messages:

adage sendmail[3245]: server smtp: showq from <internet machine>
adage sendmail[3245]: server smtp: unrecognized: debug from <internet machine>

I think that the worm which was so widely publicized last spring used the
debug option in sendmail.  So it looks to me like someone/something
was trying to get onto my system.  But I don't know for sure. Can anyone
please give me some pointers about what these messages really mean? And any
actions I should take in response to getting these messages?

Thanks in advance,
David Harris
