If I register with an email address outside of our network, such as gmail or gmx, or open a ticket, I will not receive an email. Therefore, I assume that osTicket in the version currently installed, version v1.10.1, cannot send emails to the outside ...
Within as with the email addresses of our domains (employees, etc.), the emails arrive without any problems!
Please help...
1.10.x is end of life so you should really upgrade.
That being said: You are using PHP Mail functions, which means your webservers PHP is sending emails. The relay that it is using may prohibit sending emails to external targets.
If you need to get around this, you would likely need to configure SMTP on a real mailserver instead of relying on PHP's built in email relaying.
Thank you, i know, that is my other Problem...the Upgrade to next higher version doesn't work.
How can i configure to our internal Mailserver?
Did not found anything where i could do this!
That would be a great help!
You setup an email at: Admin panel -> Emails -> Emails
You set your Default MTA to be the email configured at Admin panel -> Emails -> Settings
