[SOLVED] Filter for beginning of e-mail address

[Afox]

Hello, how can I match the beginning of an e-mail address?

For example in example@domain.tld I want to create a rule to match every e-mail address starting with example

Thanks and best regards

I tried to match it with regex like so:

^example

But the validator says it does not match the address example@domain.tld

example@.*
