Hi Guys,
So we have an old piece of software that is used for a basic reason. It compiles a file and sends it to an email address.. nice and simple.
The program requires the user to enter a couple of settings based on how will you send this file via email.
these details are the SMTP server and email address you will be sending through. as there are no port options, port 25 has been hardcoded to be used.
So for Telecom we would use :
smtp.xtra.co.nz
user@xtra.co.nz or user@gmail.com etc etc.
This has been working fine for the past 15 years! right up until Telecom decide to power off the old smtp server and replace with the new "send" server.
First thing everyone has said is change the smtp server to use send.xtra.co.nz. The problem with using the send server is our program does not offer the option to use SSL/user Authentication. So our program will not connect to that send server.
As telecom will not turn this smtp server back on they are no help!
What I have tried doing is using an online service called SMTP2GO. This server does not require authentication and you can send email through their server. smtp.smtpcorp.com
I have tested this on my PC and it works like a charm. also tested on another clients pc and works great. I have now come across some computers that it does not work on. all connected to broadband. One thing I have found is the ones that do work you can "telnet smtp.smtpcorp.com 25". the ones that do not connect and send email you cannot "telnet smtp.smtpcorp.com 25". so is it possible that telecom have port 25 open on a couple of these machines and that is why it is working?
I have disabled firewalls/antivirus scanners on the troubled computers just in case...
any ideas on how this process should work?
cheers,
Sam
