Hi Pete/Ben,

Thank you for your response. We have enabled Site-Specific logging for a few
domains but more specific we have done it for our domain (aip.org). Below is
an example of a probe failure for one of our email addresses. In this case
[log in to unmask] is a valid email address here so I am still unsure as to why
the probe fails. This is affecting many of our other lists and we are
receiving many complaints from subscribers who have been auto-deleted.

Listserv Daily Log:

17 Mar 2006 14:52:18 Distributing mail ("FYI_MAILING") from
owner-fyi@LISTSERV.AIP.ORG...
17 Mar 2006 14:52:18 Mail posted via SMTP to [log in to unmask]

SQL> SELECT EMAIL,NAME,FYI FROM LISTSERV WHERE UEMAIL LIKE ? FOR UPDATE OF
EMAIL,NAME,FYI,UEMAIL
17 Mar 2006 14:52:34 -> Probe failure for [log in to unmask] on FYI

LSMTP Accounting Log:

5 145232 1.001E5AA6 SMTP <192.58.150.56> <192.58.150.54> <> <> 21011 13
<owner-fyi*djones**AIP*[log in to unmask]> <[log in to unmask]>.

From what I understand "5" is a successful transaction.

LSMTP Site-Specific Log:

Thanks in advance for your time,
