OTRS 6: Mail problems

[mgoeppl]

Hey there, I cannot send mails, but only receive them.

My mail config:
SendMail

The message displayed in the ticket overview:
Sending of this message has failed. [23/07/2020 11:18 (Europe/Berlin)] Error while validating Sender email address.


The report after sending:

Message: Impossible to send message to: recipient@example.com .

check you sender mail address configured for the queue

Hi,

Due to the fact that you're using the Sendmail module you have to consider the MTA's log on your OTRS server. Usually, this is Postfix, Sendmail or Exim. I guess the MTA is not properly configured.

If you're not familiar with your MTA you should consider using another module like SMTP/SMPTTLS/etc.
