I should have sent this in with my first message but I was working from home and the connection was incredibly slow. Here is my system information: Platform: Windows Server 2003 SP2 Listserv Version: v15.5 I noticed this problem in my test mailing list called SampleList. Samplelist Header: * * Pomona ITS Test Sample List * * Service= pomona.edu * Ack= No * Send= Private,Confirm * Sender= None * Exit= noexitonly * Notebook-Header= Full * Digest= No * Subject-Tag= "Samplelist" * Change-Log= Yes,Daily * Default-Options= noack,repro,html,mime,subjecthdr * Subscription= Closed * Confidential= Service * Validate= Yes * Reply-to= Sender,Respect * Review= Owner * Errors-To= Owners * Owner= [log in to unmask],[log in to unmask] Subscription Options for me on Samplelist: Subscription options for Brett Watts <[log in to unmask]>, listSAMPLELIST: MAIL You are sent individual postings as they are received MIME You prefer to receive messages in MIME format HTML You prefer to receive messages in HTML format SUBJECTHDR Full (normal) mail headers with list name in message subject REPRO You receive a copy of your own postings NOACK No acknowledgement of successfully processed postings I am subscribed to the SampleList mailing list as [log in to unmask] The only thing that was changed was the setting for SMTP_Forwarding and SMTP_Forwarding_N. Both were set to our SMTP server. This setting worked on our Test Listserv server which was a VMWare copy of our production Listserv server. Our Test Listserv server sends out the confirmations without any problems. I'm still poking away at this problem but any insights would be helpful and welcomed.

The messages are ending up in the Moderation List. Once the message in the Moderation List is approved, the message is delivered to the mailing list with out any problems but the submitter confirmation is never sent out. Has anyone ever experienced this problem or have an idea what is causing it? Thank you in advance for your help or suggestions.
