Hi Scott - 

hat, let's say I want IIS to be the first to receive email from the 
Internet, and Imail second.
have the mx point to the ms smtp box and then smart host to the imail box
kabish?

-Nick



How do I set that up and still be able to send/receive email on my network 
here?

Best thing would be to configure the 3rd party software to use IIS SMTP on a
port other than 25, and leave IMail on 25.

Maybe if you reveal what the 3rd party software is, someone can assist with
the configuration of it.

I guess I'm not very good at explaining what I'm doing, so I'll try it
again.

I have this one server that runs my website and my mail services.  I want to
run some 3rd party software that does some processing of mail before it goes
to Imail.  The 3rd party software requires the use of IIS SMTP.  So I have
to have mail go to the IIS SMTP first, and have IIS SMTP forward the mail to
Imail.  In order for that to work, IIS SMTP must be listening on port 25 and
IIS SMTP must send mail outgoing on port 26, in which case it is forwarding
those messages to Imail SMTP which would need to listen on port 26.  Again,
all this is happening on one single Windows 2003 web edition server.

As far as I can tell, with this setup, I have no SMTP service that will
effectively let me have mail sent back out to the Internet, because I would
need that SMTP service to send out on port 25.

I hope that makes sense.  So my question again is, is there a way to set
Imail SMTP to listen on port 26 but send outgoing connections on port 25?
And by all means, if anyone sees something here that I'm missing completely,
let me know - I have a habit of making things more complicated than they
need to be.

I think you need to step back and look at what you're really trying to
accomplish.  What exactly is your need to have an SMTP process listening on
a port other than standard 25?

Actually, there is one more thing I need to address here.  If my IIS SMTP is
going to be set to a non-standard outgoing port, and my Imail SMTP is set to
that same non-standard port, then how would I get my outgoing email to go
through?  Can Imail's SMTP be set to listen on one port but send outgoing on
another?  If not, then I'll have a problem getting email sent outside our
network.

No, I just tested it - I shut down IIS SMTP and tried one of the scripts -
mail still went through, so it is using Imail SMTP to send the mail, not IIS
SMTP.  So no problems here.

Looks like I have everything I need now to do what I want to - thanks
everyone for your input.

If you are using PHP for web scripts then the email is probably being sent
from the PHP email engine which uses the SMTP server specified in the
php.ini file. You shouldn't be using the IIS SMTP server unless it is
specified as the mail host to send mail through in php.ini. As mentioned
earlier, if you have anything using CDONTS, recode it to use CDOSYS or a 3rd
party component such as ASPEmail if you want to use ASP or .NET to code. I'm
sure there are alternatives in PHP and PERL as well.

I'm not even sure what CDONTS is - we're actually using PHP for our web
scripts.  Having said that, I'm not actually sure that my web pages are
using IIS SMTP - the default (port 25) has been Imail's SMTP, so I might not

have any issues afterall.

Sounds like you're using CDO.  Use a standard mail component instead of CDO,
or use CDOSYS instead of CDONTS and you're not tied to IIS SMTP
anymore....so your websites can send using any mail server.

Well, I never received that email...

I wouldn't have a problem keeping outbound connections on a non-standard
port, except that my webserver uses it for my form-to-email pages on our
website (my webserver is of course on the same machine as all these SMTP
services too).  So I guess if I wanted this to work now I would need to get
my webserver to use Imail's SMTP service instead of IIS SMTP - but that is a
topic for another thread (I think I saw a lot on how to get around this in
the archives).

This thread branched off, but Sandy did indeed post this info in response to
your question.

Yes it would cause a problem, as other mail servers would be listening on
port 25, not 26.  You would need to change it back to port 25 if this is
going to be outbound to the internet.

Thank you.  I apologize for my ignorance, I thought you were referring to
Sandy's response in this email thread regarding the location of the port
setting (in which case what you've just explained was not mentioned
already).

So if I have to change the outbound connection port on IIS SMTP, would this
cause problems if it becomes the SMTP service that actually sends my
outgoing email to the Internet?  Or is the inbound port being the standard
port 25 the only thing that matters here?

IIS 6:
- Virtual Server Properties
- Delivery Tab
- Outbound Connections button
- TCP Port

IIS 5:
- Virtual Server Properties
- General Tab
- Connection button
- TCP port

Note that these _are_ the outbound connection ports.  Inbound is specified
elsewhere.

Well, then could someone please explain exactly where the setting is,
because I've looked all over the SMTP virtual server settings, and the
settings for the remote domain in the virtual server, and I don't see where
you can change the port number.  I've tried typing the IP address with a
colon and the port number following, but it won't accept that as an
address - there is no where else that a port number can be entered there.
I'm not an idiot, and I'm telling you it isn't there.

Well, I just checked and the setting is exactly where Sandy said it was in
IIS6, and I posted where it was in IIS5, so you have it available to you to
redirect as you wanted.

What I really need is for IIS SMTP to forward all messages it receives from
the Internet to Imail SMTP, and this all needs to occur on the same
computer.  Because IIS SMTP would be my main gateway, it has to listen on
port 25, but I can only get it to forward to port 25, so I'm curious to see
how I can get a utility to help me do this, because I'm having a hard time
understanding it myself.

There is a utility I am using called RelayTCP that does exactly that.

No.  I would have IIS SMTP running on port 25, and Imail on port 26.  I
need
the IIS SMTP to forward to port 26 on 127.0.0.1, but it appears I can't
choose the port that it forwards to - it seems to want only to forward to
port 25.  Sounds like SMTP in Exchange will let you do this, but I am not
running Exchange.

Does anyone have any ideas on how to get IIS SMTP to forward to 127.0.0.1
on
a port other than 25?  I am not going to install these on separate
machines,
so if this is not going to work I will have to try a 3rd party software
package that has it's own SMTP built in instead of relying on IIS SMTP.
