He was well annoyed with our ISP for complying with RFC's because they switched to ESMTP and MS-Mail promptly broke. The *ONLY* acceptable reason for terminating a connection is when you recieve the command "BYE", so when Pipex sent us the command EHLO, MS-Mail promptly dropped the connection ... Pipex, and I suspect other ISPs, had to implement an extended black list of customers who couldn't cope with ESMTP. Cheers, Wol
