I have a client who would like to perform email validation for guest sponsors - this works fine for the entire domain.However, they would like to negate certain accounts from being sponsors, mainly any account that has a "-x" or "adm-" in the username. Is this possible? I've tried the following array but if the account exists in the alloweddomain.com, then the deny array isn't checked.
array (
'allow' =>
array (
0 => 'alloweddomain.com',
),
'deny' =>
array (
0 => '*-x*',
1 => 'adm-*',
2 => '*',
),
)
