Sympa maintains web archive for mailing lists that have the feature enabled. The web archives are fully integrated in the Sympa web interface, though the engine that does the HTML tranformation is an third-party tool, MHonArc.
This is probably the most interesting part of the Sympa web archives : you can restrict access to a list web archives to a certain population (members of the current list, members of another list, intranet users, users defined in an SQL/LDAP base). This fine tuning is defined via the web_archive.access list parameter. This parameter refers to the corresponding authorization scenario.
Sympa provides a search engine to search archive of each list. User can either use the standard search field or the advanced search page. The search engine is based on MarcSearch perl library.
Sympa provides a
message removalfeature, accessible through a button from individual message web pages. This feature is restricted to either message authors (once authenticated) or list owners. Removal requests are then processed by the
archivd.plprocess ; therefore it may take a few seconds before it is removed.
From individual message web pages, you can ask that the message is sent back to you, via SMTP.
List owners have access to an archive management page from the web interface. From this page, they can download a ZIP of their list web archives. The ZIP is organized by month, each month containing original emails.
Sympa does not perform the MIME → HTML transformation itself, neither does it build the messages index and threads. All this is performed by the MHonArc program. MhonArc is a software used beside many other mailing list softwares. The may Sympa uses MHonArc concentrates on integration.
You can customize the behavior of
mhonarc-ressources.tt2resource file. The html view of archives is being delivered by the
wwsympa.fcgiprocess so the MhonArc output uses Sympa TT2 template format. When modifying
mhonarc-ressources.tt2you may change the way MhonArc prepare archives or you may change the way wwsympa.fcgi show them.
See MHonArc manual for more informations on customization.
The web archives are gathered in a common directory defined by the arc_path wwsympa.conf parameter. This directory contains a subdirecty for each archived mailing list. The list archive directory is structured a subdirectory for each month. Eath month directory contains both the HTML pages for messages and indexes and a subdirectory containing the orginal messsages in a test format.
Here is a sample list archive hierarchy :/email@example.com/: 1997-07 ... 2007-05 arctxt 1 2 ... mail1.html msg00000.html msg00001.html msg00002.html ... thrd1.html

A dedicated perl script,
archived.pl, is performing all operations on list web archives (adding a message to archive, removing a message, rebuilding HTML files). This process is running as the
sympauser ; messages to archive and removal/rebuild commands are fetched from the
outgoingspool defined by the queueoutgoing sympa.conf parameter.
When it archives the first message ever for a given list, archived.pl will try and create its archive directory. If it can't, it copies the message into a
bad/subfolder of the
Sympa provides a way to rebuild all HTML files for a given web archive. This is useful whenever you changed the
mhonarc-resources.tt2file or if Sympa changed its template format or the charset used for web pages.
The rebuild feature is accessible to listmasters only from the
Archiveschapter, from the web interface. The rebuild is then run by the
Since version 5.2b, Sympa maintains a single archive of mailing lists, but it previously maintained both a mail archive (stored in the
list_data/mylist/archives/directories) and a web archive (for historical reasons). You may need to import existing mail archives in a list mail archive, using the provided
arc2webarc.plscript. Here a small pattern on how use
arc2webarc.plto manually import archives of an old sympa server :# sympa.pl --create-list XML.for.$liste (or create $liste in web interface) # mkdir /...newlist_data.../$liste/archives # cp /...oldlist_data.../$liste/archives/log* /...newlist_data.../$liste/archives/. # arc2webarc.pl $liste
If you are moving from another mailing list software to Sympa, you are also facing messages archive import problems. Check the Contrib section for useful migration tools.
