Why does the mail stay in the queue? gmail.co does resolve. right?

If you know addresses are "invalid" why don't you reject them
directly, e.g., using
mailertable Include a "mailer table" which can be used to override
....
error:code message
error:D.S.N:code message
will give an error message with the indicated SMTP reply
code and message, where D.S.N is an RFC 1893 compliant
error code.

Anyway, if you want to figure out whether ".REDIRECT" works
in your setup, use sendmail -bt and something like
3,0 user@gmail.co
/tryflags er
/parse user@gmail.co

If that doesn't give you a clue where the problem is, post the
output here and explain which result(s) you expect(ed).
