[Exim] Problem with 'HELO' (Lotus Notes)

I'm have a problem with a particular corporate mail server connection
that is being reported as a "501 Syntactically invalid HELO
argument(s)"


Listening...
Process 16456 is handling incoming connection from [207.61.58.162]
checking for IP options
no IP options found
LOG: smtp_connection MAIN
SMTP connection from [207.61.58.162] (TCP/IP connection count = 1)

Thanks for any help... ;-)
