[Typo3] cron job fpr direct mail

[Maik Caro]

hi,

when I try to execute the dmailerd.phpcron I get the Error Message

Wrong path... This 'sr/sbin' should be the last part of '/usr/sbin'

After I changed the $dir
$dir = dirname("/var/www/typo3/ext/direct_mail/mod/");

I get the Error

Wrong path... This 'typo3/ext/direct_mail/mod/' should be the last part 
of '/var/www/typo3/ext/direct_mail/mod/'

the first path is part of the second, so I don't understand the Error 
Message.

Does anyone has the cron job successfully running?
