Wildcard / Regex in Filters

Wildcard / Regex in Filters

Hi,

I'm getting a lot of spam with recurring substrings in words but not recurring words.

I need an email filter of the type "*xyz" where * means any characters, so it would trigger on both "abcxyz" but also "lojasdbgfgxyz"

How can I do this? What wild cards or reg ex are supported? If not on Zoho Mail directly, maybe on the admin panel?

Thanks
Paul
