With the growing number of checks that can be switched on and off, the parameter list has become somewhat long and cluttered, switches are named use_*, check_*, or skip_*, and also some have to be set to True to enable a test, some to True to disable the test.

I had the idea of replacing all these parameters with a single one:

First, we define a constant for each of the possible checks:

CHECK_FORMAT = 1
CHECK_BLACKLIST = 2
CHECK_MX = 3
CHECK_SMTP = 4
CHECK_SMTP_COMMUNICATION = 5
CHECK_SMTP_TEMPORARY = 6

and we define the default set of checks as a Python set:

CHECK_DEFAULT = {CHECK_FORMAT, CHECK_BLACKLIST, CHECK_MX, CHECK_SMTP}

Then, we can change validate_email_or_fail to accept the parameter checks: Set = CHECK_DEFAULT.

Downside: this would either break compatibility with previous versions, or we'd have to accept both options for a while, adding a deprecation warning when the old parameters are used.

What do you think?
