OT: sendmail: possible SMTP attack??

[Jeff A. Earickson]

Gang,

I've been seeing a ton of "possible SMTP attack" syslog messages
from sendmail for the last couple of days, from all over the
place (mostly Isreal and Brazil).  Normally, I almost never see
this message from sendmail.  Anybody else seeing this?  New
email virus???  Any other ideas?
