Hold mail delivery I have a Postfix relay server setup and need to perform some maintenance on my production mail server this weekend. During this time, I don't want mail delivered to the server from my Postfix relay until I am done. How can I tell Postfix to continue receiving and queuing mail, but not deliver it to my mail server? Thanks! jlc >From dnrxv_ttnx@yahoo.com  Sun Feb 24 10:30:42 2008 Message: 4 Date: Sun, 17 Feb 2008 12:52:15 -0800 (PST) From: rafiqul haque  Subject: [Wekalist] Reducing  dataset To: dlnirllc@waikato.ac.nz, "Weka machine learning workbench list." 	 Message-ID: <838732.60967.qm@web30008.mail.mud.yahoo.com> Content-Type: text/plain; charset=iso-8859-1 Dear Peter Thank you very much for your solution. Actually, I am dealing with a large dataset that has been statistically collected and analyzed. Now my responsibility is to analyze same dataset using data mining approaches. The main problem is, I am new in data mining and not being able to understand how am I going to reduce these data. Any suggestion from your side will be very valuable.

I have read that to get instance specific predictions a test set must be provided.  Is there an easy way to use the cross-validation and also get classification predictions for specific instances in my data set?
