Hi All,
 
Have ISA Enterprise Edition installed on Windows 2000 Server for the
last six months without major problems.
 
Without alterations to the configuration, in the last few days have
started to receive inexplicable "ISA Server Alerts: An Unknown SMTP
Command" for HTLM e-mails. e.g. This morning received 400 "Alerts" for
an email from IP 207.46.248.65 (Microsoft) for a HTLM Newsletter:-
 
1.    ISA Server name: AVEROMAR02   BDAT 16694
 
2.    ISA Server name: AVEROMAR02    THU, 11
 
3.    ISA Server name: AVEROMAR02    RECEIVED:
 
399.    ISA Server name: AVEROMAR02    </HTML>
 
400.    ISA Server name: AVEROMAR02    </BODY>
 
Any suggestions of where to look for the cause of the problem welcomed
 
David.
