configuring ssmtp on Ubuntu to use zoho

configuring ssmtp on Ubuntu to use zoho

I am trying to configure ssmtp on my Ubuntu server to use my email hosted by zoho, but I keep getting "535 authentication failed" errors.

Doing 
$ tail -n 24 /var/log/syslog
shows:

This is what /etc/ssmtp/ssmtp.conf looks like

  1. Debug=YES
  2. root=kurt@kurttest.com
  3. mailhub=smtp.zoho.com:465
  4. rewriteDomain=zoho.com
  5. UseTLS=YES
  6. AuthUser=kurt@kurttest.com
  7. AuthPass=********
  8. UseSTARTTLS=NO
  9. FromLineOverride=yes

And this is what /etc/ssmtp/revalias looks like

  1. root:kurt@kurttest.com:smtp.zoho.com:465

Any help would be appreciated. Thanks.
