Is it Evolution or Thunderbird (actually at 5 million in a folder it probably is). Any simplistic manipulation of a maildir with 5,000,000 messages in maildir will require 5 million file reads (if only the headers). Some IMAP servers maintain indexes of some information, if the information you want to search on is indexed by a common IMAP server then this is probably the way to go for creating an index on the fly. Otherwise there are Perl and Python libraries to manage maildir. Simon -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
