I'm a newbie in the OTRS installation, I juste used it before for the work and I want to use it in my organization now.
I installed it successfully and postfix too.
I'm on Ubuntu 20.04, on a dedicated server.
But when I want to send an email (creating email ticket) I get this message :
Code: Select all
10 Kernel::System::Email Error sending message using backend 'Kernel::System::Email::Sendmail'. 11.07.2021 17:01:04 (Europe/Paris)
11 Kernel::System::MailQueue Message could not be sent! Error message: Can't send message: ! 11.07.2021 17:01:04 (Europe/Paris)
12 Kernel::System::MailQueue Temporary problem returned from server, requeuing message for sending. Message: SMTPCode: -, ErrorMessage: Can't send message: ! 11.07.2021 17:01:04 (Europe/Paris)
Maybe a bad config of Postfix, but I can send email with the command-line, so I don't think that the problem comes from there.
Hope someone will be able to help me!
If you have any questions, don't hesitate.
