Fallo envío de invitaciones Alfresco

[isaacgrods]

Hola,

Les cuento un problema concreto que tengo con Alfresco después de leer muchos hilos dentro de este foro y no haber podido dar con la solución: Valga por delante que soy un usuario totalmente amateur en Alfresco y estoy diseñando, por primera vez, un sistema de gestión documental para una empresa.

El caso es que trabajando tanto con la versión Community 5.0 (en sus variantes a. b. y c.) como con la versión 4.2.c (también Community), no consigo que los usuarios reciban el mail de invitación para participar en los sites. 

He seguido todos los pasos que se comentan en este foro para casos similares:

https://forums.alfresco.com/es/invitar-un-usuario-03012011-0938

Tras seguir los pasos de cada uno de esos hilos, en diferentes ordenadores, no consigo solucionar el problema.

En mi caso concreto, al crear la invitación desde el administrador, me sale el mensaje: "(1)invitación enviada, 0 fallos". Pero nunca consigo que lleguen las invitaciones, con lo cual nadie de la empresa puede acceder al sitio Share de Alfresco creado al efecto.

Estoy bastante desesperado, ya que tras dos semanas de intenso trabajo, no puedo entregar el producto al no dar acceso a ninguno de los miembros. Solamente entrando a Alfresco desde mi ordenador con su usuario y contraseña es como he conseguido aceptar las invitaciones y que formen parte de un Site. 

Si alguien pudiera orientarme al respecto, o sugerir nuevas vías para solucionar el problema,les estaría muy agradecido. Debo entregar el primer reporte de Alfresco el Lunes y necesito urgentemente dar solución a este problema de las invitaciones, para que los usuarios de la empresa puedan empezar a trabajar con Alfresco. Vivo en Madrid, así que igualmente, si alguien estuviera disponible antes del Lunes, podríamos acordar una tarifa por hora y ayudarme a solucionar el problema y aprender los pasos para la próxima vez.

Muchas gracias.

Un saludo,

Isaac

Buenos días, IsaacGrods.

Antes de nada, échale un vistazo a este enlace donde te explican como se configura el correo en alfresco. Verifica que tu instalación es correcta (repasa que los archivos estén configurados, etc..).
Además d ela configuración puede ser problema de tu firewal, en el caso que tengas habilitado en tu servidor. Vamos a intentar llegar a lo que produce el problema.
Lo siguiente que te voy a proponer es: Arranca tu alfresco, invita a alguien y una vez tengas la pantalla péganos aquí el catalina.log y el alfresco.log a ver si vemos cual es el problema.

Un saludo.

Buenos días, Cristina MR

Muchas gracias por tu respuesta y ayuda. El link que me envías ya lo había utilizado para configurar el correo saliente y tampoco hallé la solución a través de ese post. Justo acabo de realizar una invitación a un Site en Share. Perdona mi torpeza tecnológica, pero quieres que te envíe el contenido entero del .txt de alfresco.log y de catalina.log?

Muchas gracias de nuevo

Estimada Cristina,

Éste sería el contenido del archivo alfresco.log

El error que tienes es este: (en el alfresco.log)

Caused by: javax.mail.MessagingException: Unknown SMTP host: smtp.example.com;‍

Puedes pegarnos aquí la configuración que tienes?

P.D.: Un truco, cuando quieras poner código hazlo entre los tags

 y ‍

(sin espacios) 😃

[isaacgrods]

Muchas gracias por tu respuesta, CristinaMR

La configuración que he realizado ha sido la siguiente:

1.- Archivo alfresco-global.properties:

### Outbound mail SMTP ###
mail.host=smtp.ud-h.com
mail.port=587
mail.protocol=smtps
mail.smtps.auth=true
mail.username=isaac.garcia@ud-h.com
mail.password=password
mail.encoding=UTF-8
mail.from.default=isaac.garcia@ud-h.com
mail.smtp.starttls.enable=true

Al final de ese archivo (global-properties)también añado:

### Test message when Alfresco starts ###
mail.testmessage.send=true
mail.testmessage.to=isaac.garcia@ud-h.com
mail.testmessage.subject=Outbound mail from Alfresco, server started.
mail.testmessage.text=Outbound SMTP email subsystem is working. Installed on ${dir.root}

2.- A continuación, entro en el archivo (alfresco-global) y sustituyo:

### E-mail site invitation setting ###
notification.email.siteinvite=false

Por

### E-mail site invitation setting ###
notification.email.siteinvite=true

Eso es todo. Evidentemente, ni me llegan los mails (los usuarios están en e-mail contribuitors)una vez arranco Alfresco ni le llegan las invitaciones a los usuarios. Ya no sé ni qué más poder hacer.

Espero más o menos hacerme entender, como te comentaba esta mañana, soy totalmente ignorante en estas cuestiones.

Muchas gracias por tu tiempo y tu ayuda.

Puedes ejecutar esto desde tu servidor?

ping smtp.ud-h.com‍

De todas formas, el error de más arriba no concuerda con la configuración que me enseñas, a lo mejor es anterior.

[isaacgrods]

Buenos días, Cristina MR

He ejecutado ping smtp.ud-h.com y he aquí el mensaje que me devuelve: <La solicitud de ping no pudo encontrar el host smtp.ud-h.com. Compruebe el nombre y vuelva a intentarlo>.

Paralelamente a ésto, te cuento los "avances" y pruebas que he realizado. En dos ordenadores personales he instalado también Alfresco 4.2.c. Para hacer pruebas sin impactar en la de ud-h.com, he utilizado un post tuyo de este foro donde dabas las instrucciones para configurar desde Gmail. He seguido las indicaciones y configurado tal y como tú mencionas. Y nada, en ninguno de esos dos ordenadores funciona tampoco. Incluso realicé la prueba de abrir un mail en gmail y copiar y pegar tal cual tu configuración: el error que me da al intentar enviar el mensaje es el siguiente: no reconoce el host=smtp.gmail.com

Con lo cual mi grado de desesperación aumenta con el pasar de los días. No sé qué puedo estar haciendo mal y qué nuevas pruebas podría realizar.  Lo curioso es que en las pruebas de Gmail he consultado también el alfresco.log y el catalina.log y no me da ningún tipo de error.

¿Te sirve de orientación estas pruebas? ¿Qué nuevas vías me puedes decir al respecto?

Finalmente, también he consultado y seguido los pasos de configuración (a modo de prueba usando cuenta de Gmail) que señala este blog: http://www.fegor.com/2011/05/uso-del-correo-electronico-en-alfresco.html

Obviamente, tampoco me ha solucionado el problema,

Muchas gracias por tus comentarios y aportaciones. Te estoy muy agradecido.

Que tengas buen día.

Isaac

No desesperes y ten paciencia 🙂

<La solicitud de ping no pudo encontrar el host smtp.ud-h.com. Compruebe el nombre y vuelva a intentarlo>. ‍

Eso significa que NO encuentra/no llega la señal a ese host, esto puede deberse a varios problemas. Vamos a intentar averiguar qué es.

1. Puedes por favor hacer un ping www.google.com y decirme que te sale? Esta vez, el resultado mételo dentro de los tags

 y ‍

.
2. Tienes instalado un firewal?

Espero ambas respuesta.

Un saludo!

[isaacgrods]

Estimada Cristina MR,

En primer lugar, por favor disculpa la tardanza en responder a tus consejos. Finalmente, gracias a la inestimable ayuda de un desarrollador, conseguí que funcionase el envío/recepción y aceptación de invitaciones. Tal y como creo que intuías tú, uno de los problemas (aparte de fallos míos en la configuración) fue que el Firewall estaba activo con lo cual impedía la salida de invitaciones. Una vez desactivado el Firewall, las invitaciones han podido realizarse de manera adecuada.

Con lo cual, ese problema fue resuelto de manera satisfactoria. Luego me he encontrado con un problema más gordo, más "estructural", digamos, con el que quiero hacer una consulta en el Foro, buscando la opinión de todos los que sois expertos en Alfresco.

Nuevamente, disculpa la tardanza en contestar.

Agradezco mucho la ayuda que me has brindado.

Un saludo,

Isaac
