Hello admins,
Please look into the extension file types we can attach to a message. There are numerous which can be safely attached without any problems. I cant comment how many though, but the most prominent one which needs to be included soon is “rar”.
Currently allowed ones:
bmp doc gif jpe jpeg jpg pdf png psd txt zip
Others which can be safely attached:
rar xls inf
Others may add more extensions which are safe to attach.
