If you can't find auto created issues, check here: with admin account open project>issues>analysis.

Check value for max_cron_threads config. It should be non-zero.

Thanks for the responses guys, unfortunately, the automatic Fetchmail functionality is already setup and running, but no trigger is actually registered.

The automatic incoming messages used to work perfectly fine before. I'm not sure when it stopped working whether being after an update or we switched our Amazon servers location (we transferred an image of our OpenERP server to another Amazon server location)...Not sure if that would break anything however.

What puzzles me in that OpenERP is not showing any attempt to fetch emails automatically. At least that's what the "Last Fetch Date" shows.

Any other thoughts?

"the last fetch date" is showing only the last SUCCESFULL time and date the system was able to fetch e-mail.

With other words, it might try to fetch just every few minutes, but has maybe a problem to succesfully end the the fetch process. 

Just check your logfile/console to see if you see that the fetchmail is executed. If it executes, but gives an error, you proberly have to remove the first e-mail in your e-mail box. (I had one with some strange spam garbage in it, wich causes fetchmail to abort, had something to do with wrong UTF-8 encoding). If you are paying attention to the console, and try to force the fetch you can actually see what happens.

After removing the e-mail which was causing this, all went well. 

Worked for me....

I went to Setting>Modules>Installed Module>Base and Upgraded

Dont know what happened but its working again!

I'm searching for this automated actions everywhere in 8.0dev-20140416-230101

I can see under apps that a plugin "  

Automated Action Rule " is installed, but I can't see any hint to neither "schudule", "automation" nor fetchmail in my "Settings" 

so where can I search to get the settings of the automated tasks in Odoo v8? 

all the best for you guys!
