Are mail filters case sensitive

I couldn't find anywhere if terms used in mail filters are case sensitive or not? Example, I set up a filter: Any Header contains Brain Stimulator will that be true for "brain stimulator"? or do I need to use regex for case insensitivity?

  Hello :) When creating an account or user-level filter in cPanel, the words "is", "matches", "contains", "begins", and "ends" are written in lowercase to the file at /etc/vfilters/${DOMAIN}. This allows for case-insensitive matching. Thank you.

  Thanks for the reply, Michael. I tried to find the file you describe, being a curious fellow, but did not see a vfilters directory under etc. I did find a filters.cache in the .cpanel directory which does seem to contain my account-level filters. I'll grant that maybe I'm not understanding your explanation and the file to which you refer lies upstream only within the purview of the cPanel code and/or database. The file I did find within /home/[username] is as follows. File Manager View shows: filter.cache perl Storable(v0.7) data (network-ordered) (major 2) (minor 9) And the file begins with the "Brain Power" filter: pst0 C /dev/null dest save action actions Brain Power filtername 1 unescaped containsmatch $message_headerspart oropt Brain Power val rules 1 enabled /dev/null dest save action actions My hope is that this filter would match "Brain Power" or "brain power" and so forth. Thanks.

  The /etc/vfilters directory is only accessible with "root" access to the server your website is hosted on. Case-insensitive matching happens by default with filters created in cPanel. Thank you.
