i have a problem with cron job. the script is executed and doesn't return any errors but it doesn't proccess my queue either. What could be the reason for that?
it looks like that you have a problem with email server, because if the script is running without problems as you said, then only problem that you have is with sending mails.Are you able to send other mails from magento system,from command line or simple php script? Without any other information I am afraid that I will not be able to help you.
