Restrict some file extensions


  • Used Zammad version: 6.2.0-1707987827.798dd740.bullseye
  • Used Zammad installation type: (source, package, docker-compose, …) package
  • Operating system: Debian 11
  • Browser + version: all

Expected behavior:

  • restrict some file extensions while opening a zammad ticket

Actual behavior:

  • all file types are allowed as an attachment

Steps to reproduce the behavior:

  • open a new ticket
  • select an attachment
  • add any file

I would like to know if it is possible to restrict the file extension when opening a zammad ticket.
For example now I can add an .exe file and I would like to prohibit the addition of an .exe file
Could you help me ? I can’t find anything in the admin interface or in the zammad documentation.

Hi @Alejandra. AFAIK t is currently not possible.
