Suitable SMTP Gateway for ecommerce?
Posted on 2010-04-02
So we have an environment consisting of about 10 IIS webserver servers, each running local IIS SMTP.
A frequent requirement we have from customers or during troubleshooting is logging confirming sucessfully email sending. Whilst IIS SMTP is pretty good at logging failures, it doesn't log sucesses and its resending methology is questionable in my opinion. I wouldn't mind some stats to get a better idea of the volumes of mail our customers send out too, failures etc.
What I want to do is add a dedicated mail server to our environment. It can either be a windows app or Vmware applicance, (or a linux app if you really must). The machines would be VMs in any case.
Uptime is a must, it must have higher uptime than our webservers, so I think I might need some kind of active/active two machine setup with a virtual IP as well. Or can IIS try the smarthost then fall back on direct send?
As this is only relaying emails from webapps, no spam filtering is required or mail box type features.
So, suggestions for apps / deployments?
