Issue Horde creates attachement for e-mail text body

Server operating system version

CentOS 7.9.2009 x86_64

Plesk version and microupdate number

Plesk Obsidian 18.0.43.1

Hello,

I'm currently using Plesk Obsidian 18.0.43.1

When we receive an e-mail on a horde mailbox the text only appears as an attachement and we need to click on it and download it to see it. What can be the problem?

I've seen this fix ( Email messages sent in plain text are not displayed in Horde Webmail: Cannot display message text ) but the content in my files doesn't match up

Thanks for the help
