Marc again dropped last time modification header, so it's impossible
to sort results by date (in general case ) without specific parser.
Also, he changed template for message. These changes cause recrawling
the whole archive each time and overloading archives.postgresql.org
More specific search engine could use another source of information which
messages to crawl, but one we use at pgsql.ru is a general search engine
and it can't get modification date without proper header.

I suggest:

1. Use 3-server architecture (image server, frontend, backend) which
   could be reduced to 2 servers (image+frontend, backend) -
   frontend could be plain apache+mod_accel and serve/cache all backends
   outputs, backend is a modperl or/and php enabled apache.

2. return last modification header - be friendly to crawlers and browsers
3. stop changing message template
