Check_MK: Check Email Delivery: FileNotFoundError

Plugin: HTTP, TCP, Email, … > Check Email Delivery

If I create a new rule and save the setting: Check Email Delivery > Name with a containing slash /, for example: Test E-Mail Send/Receive, the host service/plugin check results in a exception:

Status detail: Unhandled exception: FileNotFoundError(2, 'No such file or directory')

If I remove the slash /, for example: Test E-Mail Send and Receive, everything works as expected.

Check Mk: v2.0.0p21 (CFE)

AFAIK the / is not allowed in service names. Should be filtered at input.
