Is that what's happening here too? One of my clients has been experiencing problems receiving email from someone at a webTV account. The log typically shows: 14:44:11 4 SMTP Line 41250 created for answering 14:44:11 4 SMTP-250() Got connection from [209.240.212.83:61700] 14:44:11 4 SMTP(tcp) Connection accepted from [209.240.212.83:61700], seq=38979, 10/11 14:44:11 4 SMTP-250([209.240.212.83]) Sending 220-Stalker Internet Mail Server V.1.8b9d11 is ready.\r\n220 ESMTP is spoken here.

No sooner do we send "...pleased to meet you" than we bail out noting "Nothing read". Should this be happening so quickly after "...pleased to meet you"? ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
