"teste@test.com, alf@test.com, joe@teste.com".split(',')
=> ["teste@test.com", " alf@test.com", " joe@teste.com"]

Notice the white space at the start of all but the first email address.

With that whitespace there, the /^ in your regex won't be satisfied.

You probably want do split more like this:
"teste@test.com, alf@test.com, joe@teste.com".split(/\s*,\s*/)
=> ["teste@test.com", "alf@test.com", "joe@teste.com"]
