Folks, I'm having trouble tracing down a problem subscriber and I wanted to see if any list member could offer some tips. [...] is there any way to trace this below message back to a specific mailbox that can be removed?

if you have access to a linux/unix box you can try the program "vrfy" URL ftp://ftp.nikhef.nl/pub/network/vrfy.tar.Z URL http://www.nikhef.nl/user/e07 which will trace an e-mail address through mail servers, proxies and the like. It also allows for checking all e-mail addresses in a file (check its documentation). Nonetheless, note that broken servers could impede vrfy to complete its job. For instance, a suitable command line could be, $ vrfy -R -vvv -dHn someone@att.com rcpt 'someone@att.com' at 'kcmsi1.att.com' smtp phase connect connecting to kcmsi1.att.com (192.128.134.69) port 25 connected to kcmsi1.att.com smtp phase greeting wait <<< 220 kcmsi1.proxy.att.com ESMTP AT&T IPNS/MSI-3.0 ; Fri, 21 Dec 2001 03:09:57 -0500 (EST)

Recipient ok RSET smtp phase RSET wait <<< 250 2.0.0 Reset state QUIT smtp phase QUIT wait <<< 221 2.0.0 kcmsi1.proxy.att.com closing connection

and a more verbose one would be `vrfy -R -vvv -dHn someone@att.com` which will interact will all possible mail exchangers.
