I am using egrep -if to test for the presence of email addresses
in a whitelist. Once I get to about 200 entries in my whitelist,
then the process time is about 4 seconds but doubles with
250 entries. Some of the entries are regexes like:
(_dot_)*(_at_)domain\(_dot_)com, but this seems not to be a time-expense factor.
Whitelist could easily grow to thousands of entries.
Someone suggests look that does binary searches and this looks
like a good solution but does not support regexes.
What is the best solution here?
