Re: Multiple SMTP Connectors

In article <ePKOfkWSGHA.4384@xxxxxxxxxxxxxxxxxxxx>,
andrew@xxxxxxxxxxxxxxxxx says...
We are trying to assist a client who has just taken over multiple franchise
locations into one company, inheriting a domain name which it is
commercially unfeasible to change. They inherited a pop3 box facility which
was being accessed by SBS POP3 connectors nationwide, and which has been
letting them down badly, unfortunately ably aided by the web hosting
company. :-( We have to leave that situation asap.
We can't do too much due to the company structure still changing quite
rapidly.

1. I know I can point the domain to one the SBS2003 box at Site A; let's
say it's f-edup.com.au. That box can then forward via contacts to other
sites. Easy!

2. Now to back this system up, the ISP says I could use a secondary mx that
pointed to Site B's ip address, keep port 25 shut at Site B and any mail
coming in would not go to Site B. If I needed to use site B (which I
remotely control) becasue A was down, just open port 25 and Viola!!! it will
work instantly. No four hour lag with changing the mx addresses etc. In
this scenario the amount of email is not large, but timeliness is
everything.

Problem A: my non technical head says there will be lots of bounces from
site B? Would this be the case, or does the secondary record only get
"used" if A is not answering? I don't want to cause anymore problems than we
already have!

Problem B: The ISP has forgotten Site B needs to accept the forwarded email
from Site A in the normal course of events! Can I have an extra SMTP
connector at Site B that normally works on say Port 35 to send and receive
mail? Does that mean that I need to do something at site A so that it
forwards mail to Site B, in the normal course of events, on Port 35.

Many thanks if anyone has any ideas on this.... or even other suggestions,
come to that.

Hi, you should post to the SBS 2003 NG
(microsoft.public.windows.server.sbs).

But yes, your setup sounds all dandy to me. You can setup multiple
domains to get email from easily (you've done one already). To ensure
you have a 'backup' collection at your ISP, yep they are right too -
just ensure you have the priority levels set correctly (so that if the
SBS server is down, it drops to the ISP - which you get via the POP
connector when you're back up again.).
