It shouldn't really matter, though, because sending hosts will retry for a while themselves if they can't contact your SMTP server. If you use the IIS SMTP Service on a Proxy Server to relay SMTP, then you need not expose Exchange to the Internet. It really is a pretty good way to go.

You think it helps to point the MX record at the ISP's machine and then to our proxy or directly at our proxy and let it translate to the Exchange Server. Or does it really not matter as long as the mail is being delivered. Secondly...Is it a better idea to keep the Exchange Server behind the proxy or multi-home it and expose the other side around the proxy? I would think yes but....I do not know what other effects or limitations that poses.

I prefer to have the IIS SMTP Service that ships with the NT Option Pack relay SMTP instead of installing the MSP client on the Exchange server. You can put this service on the same box as the Proxy server if you want. See the FAQ Appendix H and Q198415 for more information on this.

I know there are a lot of opinions but I have worked on several small implementations where an exchange server was multi-homed around a proxy/firewall to provide mail service and that has always worked well but did expose the exchange server to the internet. I now have a client who has an ISP holding the MX record and points to their(the ISP) own machine. They are then IP forwarding through MS Proxy(on the client site) to an exchange server (5.5 sp3) on the other side of the proxy. The mail seems to work fine but the ISP is going away and we need to decide if this is a good configuration to try to maintain with someone else or should we make a change now since a the ISP change is being forced on us...? Any assisance would be greatly appreciated. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
