Many on line email providers don’t allow you to use their accounts with POP email clients such as Thunderbird 3.1. To solve this “matter” we have a couple of possible solutions: FreePOPs and WebMail. Today, we will discuss about Webmail that we tested on Ubuntu 10.04 LTS and Windows XP. WebMail is substantially a Thunderbird’s add-ons but it is not featured by Mozilla. Using this add-on you are able to manage Yahoo, Hotmail, mail.com, GMail, Libero, and AOL email accounts. The installation is similar in Ubuntu and Windows; on both, you have to install the core WebMail add-on and restart Thunderbird then you can add all the other components (Yahoo, Hotmail, etc..) you prefer. Then you have to modify the Thunderbird server settings following the instructions provided by WebMail:
POP
Server Type : POP
Incoming Server: localhost
UserName : username@domain
SMTP
Server Name: localhost
UserName : username@domain
Do not forget to set the Connection Security to None.
Only on Ubuntu, you need also to manually modify the incoming and outgoing ports because when you use Thunderbird through WebMail on Ubuntu, you will have a “could not connect to server local host; the connection was refused” message. This problem can be easily solved substituting the default ports on both WebMail add-on and Thunderbird ports:
– Thunderbird —> Edit —> Account Settings. Highlight the account you want to manage and go to Server Settings. There you can modify the POP Server Mail port setting it to a number bigger than 1000 (in my case I put 1250). Then go to Outgoing Servers and Edit the SMTP account you want to modify (I changed the default port to 1025).
– Thunderbird —> Tools —> Add-ons —> WebMail —> Preferences and put the same port numbers you have set on the previous step.
All this because ports below 1024 seems to be blocked on Ubuntu (if you know why, please post a comment).
For security, restart Thunderbird and it will immediately download and send your emails. Last but not least, if your on line email account is not supported by WebMail, do not forget to try FreePOPs.

Hace unos días he encontrado esta nueva aplicación para Linux, se llama CLI Companion. Aunque Linux ha evolucionado muchísimo y hay que reconocer que ya casi no hace falta hacer uso de la Consola para ejecutar programas y tareas varias, pero también hay veces que gracias al uso de la Consola se puede solucionar pequeños problema que de otra forma seria bastante mas complicado. En esos casos CliCompanion nos hecha una mano añadiendo una lista con diferentes comandos junto a nuestro terminal. La lista de los comando no es infinita, viene con unos cuantos; para cada comando hay una referencia donde se explica la función, también es posible añadir comandos y los parámetros correspondientes. Además CliCompanion tiene un apartado de búsqueda donde es posible encontrar el comando que mas nos interese en cada momento. Desde cuando lo instalé en mi Kubuntu 10.04, tengo que confirmar que es una muy buena aplicación y puede ser instalada con lo repositorios correspondientes y tener futuras actualizaciones o directamente através el paquete .DEB. Os dejo el enlace de la Web:
