[cisco-voip] SMTP relay

[Lelio Fulgenzi]

Very cool about the gmail relay service. Will have to look into that.

Question though - are your servers not on private address space? Are they then NAT/PAT'ed to communicate out?

AFAIK, RTMT cannot be authenticated.

I wouldn't trust a windows solution, especially a free/low cost one.

To me, an SMTP appliance is no better than me installing linux and setting it up, unless it is smart enough to auto update itself and protect itself (install and forget).  I'd hate for one of my customers to have issues with an email server getting compromised and spamming out their network.

But, you pointed me to just googling an smtp appliance, which I didn't think to do, and found this article at google : https://support.google.com/a/answer/176600?hl=en which details SMTP relay to google with various options.  Has anyone used this and how reliable is it?

Good thoughts, but let's see if someone else has ideas.

Some things that pop into mind:

- can rtmt be configured with authenticated smtp server? That would/should allow you to use any mail system (including off prem if routable rtmt host)

- Google smtp appliance. I tried doing this a while ago and found some options.

- look for a Windows solution. Windows is easier to keep patched. *tongue in cheek* there are usually windows experts around. As long as the o/s is patched and the f/w is set so that only rtmt host can connect, should be ok. You can go so far as to deploy on a small laptop with flash drive with  wired, wireless and 3/4G  connectivity to ensure that messages always go out. Battery backup helps in case of power outage.
