Hello,

i just found another possible email problem that could cause some of the trouble you are 
experiencing.

The php-cli which is used by typo3-cli and the sceduler aswell has a seperate php.ini 
which by default has a low meory limit. In edge cases that causes the strange situation 
that caretaker performs the tests and updates the nodes but the php process gets killed 
before the mails are sent which happens after all tests.

The problem can be difficult to find since error-logging for php is off for cli mode at 
least on debian, so you will not find the memory-errors anywhere.

Since you will usually enter a specific node id on the cli during manual testing and not 
"root" you will recieve mails on manual cli-ececution but not on cron-run for the whole 
nodetree.

To avoid this check:

- Set the memory limit in php.ini for cli to 64MB or 128MB.
- Add error logging php.ini for cli.
- Check that the cronjob-user cron can send mails.
- Execute the cli manually and see wether you recieve mails.
