How to send external e-mail from device? (Exchange 2003)

emailexchangeexchange-2003

I'd like to get external notifications on my iPhone from service monitors inside the network. The easiest way to do this is to have the devices send e-mails to my ATT SMS email (xxxxxxxxxx@txt.att.net).

However, while internal notifications work fine, it doesn't seem as if Exchange is allowing the relay of these messages to the outside world.

How can I have these devices (APC Matrix, Servers Alive, et al.) alert me anytime?

Thanks.

What you're trying to get done is referred as allow SMTP relay. Normally exchange SMTP Virtual Server is configured to allow relay only from authenticated senders and quite often the devices sending out e-mails don't authenticate with the server they're relaying through.

There's quite an easy way to achieve this, and that's called allowing IP relay on Exchange.

  • Open Exchange ESM, navigate down to the SMTP Virtual Server that'll be used to relay
  • Open the properties of that SMTP Virtual Server, and then on Access Tab locate the section about 'Relay'.
  • There you'll need to list down IP Addresses of devices and servers that'll need to relay out to external e-mail domains

Once exchange is configured on the devices you can use the exchange server IP/FQDN as a relay host for these outgoing emails.
