The output of postconf -n is preferred. > relayhost=smtp.gmail.com OK, this indicates that you are trying to send email *through* a gmail account, not merely *to* any gmail account. If you are simply having trouble with sending messages *to* gmail accounts, you do not need or want to use gmail as a relayhost. The solution to your problem is likely to lie elsewhere.
