Enterprise 3.0 Java errors on content rule...

[meansartin14]

I created a simple content rule in my home space as follows:

If a MS Word document is added to my home workspace, send me an e-mail using the 'notify_user_email.ftl' email template.

If I add a document to the workspace, the following error occurs in the 'alfresco.log' file:

ERROR [org.alfresco.repo.action.executer.MailActionExecuter] Failed to send email to smartin

I am at a complete loss. This issue was not present in Alfresco Enterprise 2.2.0. Please help!

[meansartin14]

Anyone have any ideas? I'm sort of stuck here…

[meansartin14]

Still having this issue… Please advise. Anyone? Help!

[meansartin14]

This issue remains a problem for me.

Any helpful suggestions or comments would be appreciated. Thank you!

[meansartin14]

I'm dead in the water. This issue did not occur in Alfresco Enterprise 2.2.0.

Please advise!

If you're an Enterprise customer, you'll be more likely to get a response from Alfresco Support rather than keep bumping your own topic on the forums.

Hi,
It could be a bug. As a workaround, if you set more than one email recipient, it should work.
Regards,
Thomas.

[meansartin14]

Since I didn't post it before, here is my platform and application versions:
- Red Hat Enterprise Linux Server 5.2
- Alfresco Enterprise 3.0.0
- MySQL 5.0.45 (came with RHEL5.2)
- Java JDK 1.6 Update 7
- Tomcat 6.0.18 (came with Alfresco installation)
- OpenOffice.org 3

If you're an Enterprise customer, you'll be more likely to get a response from Alfresco Support rather than keep bumping your own topic on the forums.

I am currently using a demo version of Alfresco Enterprise 3.0.0 to develop a prototype for my customer. This customer has already purchased an Enterprise version of Alfresco, but I am developing a prototype for a sub-group within the customer. So although we are an Enterprise customer, we are also NOT an Enterprise customer.

It could be a bug. As a workaround, if you set more than one email recipient, it should work.

Thank you very much for the work around. This definitely sounds/looks/feels like a bug. Is there a way for me to submit this bug to someone at Alfresco?

Yes, we encourage people to log bugs and improvements in JIRA

Please try to provide as much information as possible, including detailed steps to reproduce if available.

Many thanks,
Mike

I have the same problem, How did you fix the problem?

I want to send an email to the space owner when someone add new content. I set the rule but it crashes. I've tried sending the notification to two users and it works fine. But I want only one person to be notified.
