Thanks Christian for your answer! Unfortunately we use an external authenticated SMTP service, so i don't have the log files. What does "SendmailNotificationEnvelopeForm" stands for? It's the first time i hear about it! Thanks again, Best regards Luca Martella luca.martella@unilabsrl.it 2007-05-16 Messaggio originale / previous message: ==================================================== Subject: Re: [otrs] Problem Date: 2007-05-15 - Time: 18.40.55 Hello, On Tue, May 15, 2007 at 05:16:48PM +0200, Luca Martella wrote:

Hello all! Since a few time, our OTRS installation stopped to send notifications by email. But if i send an Administrative Notification, it send emails correctly! Do you have any suggestion?

Do you have logs of your mail server (if your own mailserver is used)? Does it help if you set a valid mail address for the config param SendmailNotificationEnvelopeFrom Maybe the messages are dropped because of a missing envelope from header.
