I wonder if this is the result of the SMTP server not properly handling the hex encoded message, or the client properly, but not securely handling of the single dot. To do some testing on my own I would like to know what SMTP server you have teseted this on, or if there are other people out there who can change my point of view ;) TIA Enchanter_tim rlf@sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org
