No, this is all happening on an internal LAN. The client is
running Ethereal and the SMTP server is on the same subnet.
There's no ISP involved.  I think this is a PCap problem
since with no filters I see both sides of the conversation.
I've posted the question to the WinPCap-users list

You had said client.  I'm guessing their ISP isn't doing what their help
desk calls "port 25 blocking"?    McAfee 8.0 has a "port blocking" feature
that may be turned on by default actually.  If they are using other
anti-virus softwares, I've seen like a virtual port (for lack of a better
term) get created to send mail.
