In the past messages were stored both in the list directory (list_data/<robot>/list/arc) and in the directory specified by arc_path conf parameter. With version 5.x archives are stored only in arc_path dir and are used both for web and mail interface.

After distribution, messages are pushed into the outgoing Sympa spool. Archived daemon picks them and calls mhonarc for HTML version and adds an SMTP text version (i.e. a ASCII file including headers and body) of them to the appropriate directory <arc_path>/<listaddress>/<yyyy>-<mm>/arctxt/<n> where

• <arc_path> is the value of arc_path wwsympa parameter
• listaddress is the qualified email address of the list
• <yyyy> is the year number
• <mm> is the month number
• n is the serial number (each message stored in a file named 1, 2, ...)

This version is very useful where archives move or when archive formats change, etc.

You just need to move <arc_path>/<listadress>/<yyyy>-<mm>/arctxt From Sympa to WWSympa. If you are doing this using a RFC934 digest used by Sympa for email mode archives, you can perform the first step running arc2webarc.pl which is part of Sympa distribution.

• It’s probably easy to adapt arc2webarc.pl.

This problem concerns only some Sympa 5.3a.x and 5.3b.x versions of Sympa.

The happens whenever an archived message includes non-encoded 8bit characters in its Subject header field. These messages are incorrect MIME messages, generated by some email clients (including Eudora); therefore we’ve got to cope with them… The mix of UTF-8 and ISO characters disturbs Sympa’s template parser.

You should move to a more recent version of Sympa; starting with version 5.3b.3, Sympa generalizes UTF-8 and prevents such errors.
