Your mail server log will tell you why.

That is true. But we were talking about wildcards '*' in filters.

That's not what I'm saying. The '.' in "*.somedomain.com" is literal. It's not
part of the wildcard scheme. So if you block mail addresses with
"*.somedomain.com" in them, mail from "someuser@somedomain.com" will still be
allowed. The '*' is a wildcard character, the '.' is not.

That will fix it, sure.
