Ethereal is now WireShark ;) You can filter on the SMTP port (TCP 25), and the right host (MX addresses of yahoo/the other domain). This results in something like (tcpdump / low level ethereal filter):
"tcp port 25 and (host a.mx.mail.yahoo.com or host b.mx.mail.yahoo.com or host c.mx.mail.yahoo.com or host d.mx.mail.yahoo.com or host e.mx.mail.yahoo.com or host f.mx.mail.yahoo.com or host g.mx.mail.yahoo.com)" Ivo ----- Original Message ----- From: "Tracy" <[EMAIL PROTECTED]> To: <xmail@xmailserver.org> Sent: Thursday, April 26, 2007 10:18 PM Subject: [xmail] Re: Vanishing mails? > Running Xmail 1.24 on Windows 2000 Server. > > I have enough traffic that logging all the mail sessions would become > quite disk intensive.
