From what I can see, the only way to access the archives of this tz list is to download a gzipped archive of the whole thing.
One simple, attractive alternative would be to use the free services of http://www.mail-archive.com/ who already have over 4000 lists archived. Excerpt from their FAQ: How can I archive a public list? 1.Subscribe archive@jab.org to the mailing list. 2.Many lists send either a confirmation request or acknowledgement here. Take care of any confirmations that the list requires. The Mail Archive automatically detects when it receives mail from a new list..... Support for XML/RDF headlines etc is also a cool feature. It is a pleasure to read in the FAQ about their attitude towards spam, and their innovative techniques to dramatically reduce the risk that spammers will take advantage of their on-line archives.
