I am using postfix and need to send the mail using google apps smtp. I am getting errors after I thought I had set everything up correctly:

May 11 09:50:57 zedsaid postfix/error[22214]: 00E009693FB: to=<www-data@zedsaid.com>, relay=none, delay=2466, delays=2462/3.4/0/0.06, dsn=4.7.0, status=deferred (delivery temporarily suspended: SASL authentication failed; cannot authenticate to server smtp.gmail.com[74.125.155.109]: no mechanism available)

What am I doing wrong?
