configurare email

[mproject]

abbiate pazienza, ma sto provando a installare alfresco community da completa ignorante … non e' che potete consigliarmi qualche tutorial che spieghi passo a passo come configurarlo?

non riesco a far spedire le email di invito. Ho messo questa configurazione nel file alfresco-global.properties:

#
# Outbound Email Configuration
#————-
mail.host=smtp.mail.yahoo.com
mail.port=465
mail.username=xxxxxxx
mail.password=xxxxxxx
mail.encoding=UTF-8
mail.from.default=alfresco@alfresco.org
mail.smtp.auth=true
mail.smtp.timeout=30000

l'indirizzo email funziona, con questa configurazione riesco a spedire email da altri software. Quando invito un nuovo membro sul sito in alfreso mi dice "invio riuscito" ma il mail non parte e nel log compare questo:

###################################

Credo che il problema possa dipendere dal fatto che la macchina su cui è installato Alfresco non raggiunge il server SMTP.
Devi parlare con il sistemista e farti dire come poter configurare la macchina per poter fare in modo che possa contattare il server SMTP locale.

Probabilmente sarà necessario configurare un Proxy server con i parametri della JVM per fare in modo che possa uscire su web.

[mproject]

grazie mille, era proprio quello !

potresti spiegarmi ancora un paio di cose?

1) e' possibile impedire ad un membro di creare nuovi siti?

2) e' possibile forzare la lingua visulaizzata a solo inglese, senza tener conto delle impostazioni dei browser dei vari utenti?

[openpj]

1) e' possibile impedire ad un membro di creare nuovi siti?

Si, bisogna customizzare la sezione di template di Share per questo customizzando il file my-sites.get.html.ftl e modificando la sezione nel seguente modo per fare in modo che, ad esempio, solo gli amministratori possano creare i siti:

<#if user.isAdmin>
    <div class="toolbar">
        <a href="#" id="${args.htmlid}-createSite-button" class="theme-color-1">${msg("link.createSite")}</a>
    </div>
</#if>
‍‍‍‍‍‍‍

2) e' possibile forzare la lingua visulaizzata a solo inglese, senza tener conto delle impostazioni dei browser dei vari utenti?

Si, dovrebbe bastare aggiungere i seguenti parametri alla JVM:

-Duser.language=en -Duser.region=US

Spero ti aiuti a risolvere

grazie mille e scusa se approfitto ancora ….

facendo cosi' elimino il bottone "crea sito" nella finestra "i miei siti", ma non elimino la voce "crea sito" dal menu siti che compare nella parte alta, per cui gli utenti possono ancora crearli. Come si fa a togliere anche quella voce dal menu?

altra cosa: e se volessi lasciare la possibilita' di creare siti agli utenti classificati come "manager", c'e' modo?
