in version 4.5.5 I am currently not able to send emails.
A mail profile is set up correctly, but when I send a test email, it does not arrive. In the logs I don’t get an error or something like that.
When I send a document by e-mail, it does not arrive either.
I still have a backup of version 4.4.8, there the settings of the mail profile are the same and there the sending of emails works fine.
What can be the reason for this?
