"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.
have you checked the automated actions? The fetchmail action should be activated
Activate the schedulers it should be work.
Did that. No effect. Again, the Fetchmail action stops working everytime I run the upgrade of OpenERP.
Question - is it just your email thats not scheduling? - None of my schedulers are working! http://help.openerp.com/question/21748/scheduler-not-working/
Theres a lot of talk about having your server running in UTC time for the scheduler - didnt make any difference to me though!
