Hi Paul,

Those are just people connecting to the mail server then 
disconnecting.  Probably someone searching for an open relay.

The sendmail exploit looks like this in the logs ( picked one up 
yesterday ):


Mar  6 10:38:24 xxxx sendmail[836]: h26Ac6kQ000829: Dropped invalid 
comments from header address


The important bit is the 'Dropped invalid...'
