I was hoping to use Zimbra desktop to be able to forward smtp without auth on my internal network, for use with an older HP network printer that doesn't offer SMTP AUTH. I'd like to be able to receive the various email alerts that it may have. Does anyone know if this will be possible - I realise that there are many safeguards (and rightly so) to prevent open relays now, but I'm hoping that as it originates in my local network, and I can specify auth as it leaves, that this will work.
