Hi,

I am still having problems trying to get NowSMS to send emails from receiving MMS's.

My current Setup:
NowSMS Gateway that receives MMS's and sends them to MMS Users.
SMTP Server installed on the same server that receives MMS from mobile and sends it to an email address.
But the problem is when emails are sent to the address of someones phone such as username@domain.com, they do not get delivered to the persons phone. They just sit in my SMTP server.

Plesae can someone tell me how to setup my SMTP server for the following to work:

1. User composes email on thier PC and sends it to username@domain.com
2. Email arrives on my SMTP server but is not passed to NowSMS to be delivered as an MMS to the users mobile phone.

Please can someone tell me how to set this up. I have looked through the forum for suggestions, have even posted this question before, but to no avail.

Any help is much appreciated :D

Hi,

Unfortunately when you talk about going from e-mail to MMS ... the process of setting up your SMTP mail server to relay to the MMSC via SMTP will vary depending on the SMTP server that you are using.

If you establish a DNS host name for PC running the MMSC, and define a DNS MX (mail exchange) record for an e-mail domain name that resolves to the MMSC, then that is the basics of how you get internet mail routed to an SMTP mail server. (In your case, it sounds like the SMTP mail server and the MMSC are on the same PC, which complicates matters greatly. The only way that you could get that to work is to have the MMSC use an SMTP port other than 25, and then the SMTP mail server would need to have the ability to relay mail for the MMSC to the MMSC on a non-standard SMTP port. I wouldn't expect most mail servers to be able to do this.)

When you talk about MMS to e-mail ... the MMSC needs another SMTP server to act as a relay host on its behalf. Unfortunately, again, each SMTP mail server has its own way that you would configure the server to accept mail as an SMTP relay for outbound delivery on behalf of another server.

I wish I could provide clear instructions, but it is SMTP server dependent.

How about this ... you say that messages are sitting on a server somewhere ... where do you see them sitting? Maybe we can start the troubleshooting process from there.

Hi Bryce,

Thanks for replying, it's much appreciated.

I am currently using Postcast Server (Free one) for mail delivery. Can you recommend any free SMTP mail servers please?

I have a server available which could either be the Mail server or the MMSC, but you recommend that both are not run from the same server.

I can currently see the messages sitting in my mail server as they are received form mobile phones to email addresses. They are then sent to thier respective addreses with no problems. But when someone sends an email to username@domain.com, their mail arrives in my inbox because my account is set to receive anything@domain.com. I have looked in Outlook for ways to forward emails with certain addresses to an IP address (My MMSC), but I can't get it to work. It needs a correct email address (with an "@" symbol). Do you know if Outlook Express can forward mail to an IP address as this may be a work around :-)

Thanks for your help

Ok. I'm not really familiar with Postcast, but a quick look at the web site indicates that it is an outbound only mail server. So it looks like it would be a good solution for a deployment with NowSMS for getting MMS messages out to e-mail.

The problem is getting them in.

It sounds like right now you have an e-mail domain where your e-mail messages are received at a service provider, and stored into a POP3 mailbox that you pick-up using Outlook Express.

I've seen solutions in the past that could retrieve mail from this type of shared POP3 mailbox, and route them to different recipients ... but no free solutions. If you setup a separate domain name, and had an MX (mail exchange) record in DNS pointed back to the PC running NowSMS ... that could work. (Services like www.no-ip.com can be used to route e-mail into an SMTP server on a dynamic IP address.)

But I still think you would need two separate PCs for NowSMS vs. the SMTP relay server (because NowSMS expects to relay to the SMTP server on port 25 ... yet the SMTP server in NowSMS must be able to listen on port 25 to receive messages). I just don't see a way to make the combination work on a single PC.

Thank you very much for the reply. Your idea of having a server for nowsms and smtp would be the better way to work.

Thanks again,
