Struggling with blacklist regex

[t0mz]

I am trying to set up a blacklist entry for certain email addresses but don't seem to be able to find a regex which works.
I understand that my regex should cover the whole address but struggle to come up with a string which covers all email addresses beginning with 'dhl-'

Would really appreciate some help.

to match any substring in regex you need to use '.*' not just '*'

I hope this helps!

Thanks Stoiko, definitely did help!
'dhl-.*@*' seems to work!

Put it in and will monitor my log…
