IIS SMTP Smart host question

When IIS SMTP is configured as inbound smarthost for an exchange server, will it queue all inbound email it received? , what if the exchange server that its suppose to forward the email is unreacheable ? will it send non delivery msg, after failing to reach the exchange server?

I'd like to setup the smarthost to filter spam, viruses, and queue email when the exchange server is unreachable for whatever reason, and being able to forward all mails in its queue when the exchange server is back online.

Is this doable with IIS SMTP ? or should I go with some linux flavor smtp daemon?

Thx
 
I wouldn't trust IIS SMTP for anything but sending email from whatever websites are on that host.

From what you're talking about MX Logic's email services might work well for you.

That actually would work really well like you've mentioned, but I am looking for a solution that does not incur monthly cost.

MX Logic also gives you ability to read your mail in queue while the Exchange server is down, depending on how dependent your company is on email that could be huge if you have an outage.

But if it's still too much then any Linux distribution can be setup to do that pretty easily. I'd personally go with Postfix in Debian.
 
IIS SMTP will queue the message and attempt to resend based on the settings you set in the delivery tab. However it is not really designed to be front end from what I can tell. This might work ok for you if you configure the exchange server as the primary MX record and the IIS one as the secondary. I would think 2 exchange servers running in tandem would be the better solution though.

just curious, which version of exchange server are you using? Im assuming exchange 2003 since your using IIS smtp and exchange 2007 has it's own built in smtp connectors. For the email, checkout dyndns. They offer several different email services that you are looking for, such as mailhop backupmx and mailhop relay. Both of these will hold email until your server comes backup, do spam filters, and etc.

I would assume IIS is on another machine since he's talking about it queueing mail while Exchange is down... That and Exchange 2003 supports SMTP.
