Alfresco 2.0 email exception when a rule is triggered

[melkor_kp]

I configured the mail setting the values with the right values of the repository.properties.

mail.host=192.168.0.2
mail.port=25
mail.username=alfresco
mail.password=alfresco
mail.encoding=UTF8
mail.header=Proof
mail.from.default=alfresco@myorganisation.org‍‍‍‍‍‍‍

And  I configured a rule which sends an email when a file which a
specific type is copied to a location.

If I check the alfresco.log I get the following error.

ERROR [org.alfresco.repo.action.executer.MailActionExecuter] Failed
 to send email to null
org.springframework.mail.MailPreparationException: Could not prepare mail: null;
 nested exception is java.lang.NullPointerException: null‍‍‍‍

[melkor_kp]

I would like to add that this happens when a rule is  applied, for example to
send a mail when a doc file is copied to a folder.

And I want to remark that it is alfresco 2.0.

The complete error is

I've got the same problem, I am very worried because I do not find any documentation about the issue.

Does anybody know something about this strange mail error?
May be it is an error I will look at JIRA.

I've edited repository.properties directly under Alfresco\tomcat\webapps\alfresco\WEB-INF\classes\alfresco
and it did the trick.
However, I am not sure this is a proper solution.
The manual states a files under webapps should never be changed

[kayachi]

The problem probably is that you have the repository-properties bean declared in more than 1 .xml file.

For instance in the default distributed 'custom-repository-context.xml' and 'custom-db-and-data-context.xml'.

The first one declares the bean with the standard 'repository.properties' and then overrides these settings with 'custom-repository.properties' in which you put your mail-setting.

After that however the bean is re-initialized in the 'custom-db-and-data-context.xml' file, this time only with the setting from 'repository.properties'.

The solution is to have the bean declared only once and make shure that the 'custom-repository.properties' file gets loaded.

Hopefully this helps…
