At our company, we recently swapped our broadband over to Orcon.

We use a remote environment for some of our work, as we have a team across all of New Zealand.

The switchover has resulted in our scanner no longer allowing us to send copies to email and some of the printers set up through the virtual computer not connecting.

Our IT Provider and the printing company have said that all their settings are correct and it is something on Orcon's end, but all we keep getting from Orcon is that its outside of their help range.

Our IT Provider has said telnet is not working, and that is the issue. They have turned it on but it isn't doing anything.

Port Filtering has been turned off, and they also tried to port forward using port triggering, and that didn't work either.

Does anyone have any ideas that I could try? If I can't get this working they are going to make me swap to somewhere else.

Any help would be greatly appreciated.

So Scan to email not working ?

Check the mail server used is accessible from a workstation.

Is the mail server locked to your old providers IP ?

Hi, using Telnet in a raw manner over the public internet is a major security issue, hence I suspect Orcon are reasonably blocking it. I recommend your IT provider come up with a more secure method, ie a VPN or tunnel of some manner.

Edit, further to that, not sure why a scanner to email feature would be using telnet anyway, very odd.

@JessieLee

Have a look at https://help.orcon.net.nz/hc/en-us/articles/360005168154-Port-filtering-in-My-Orcon

Basically Orcon do block common ports, but it can be turned off.

Edit: I see from the OP you already have turned port filtering off.

if you open those ports externally on that list without any form of IP restriction you would have to have rocks in your head

The exception being SSH if it is 2.0 and the clients each have private keys

The last time I struck this, the printer wasn't using a local mail server and forwarding. But external via the ISP or separate provided SMTP/25

Not only do you have the port25 blocking - which may or may not be lifted, SMTP relay to other destination fails checks. Much the same as needing to adjust to ISP SMTP for outbound ISP bound email (orcon email on an xtra connection and so on)

You likely won't see the message via the printer, but it's possibly being rejected with SMTP relay not allowed. Guessing the 'experts' are checking for local open ports using telnet and the port number. But unless it's a localised mail server won't anyway.

We do not have access to the mail server, but the IT provider does.

When the modem was installed I believe all the IP address information was updated to match the old information.

@JessieLee Well I would not be surprised if that port is blocked Have you tried 465 / SSL

I changed the SMTP port on the printer to 465 and ran a connection test and it failed. The test succeeds if on port 25.

Is there more i need to change when doing this than just the port number on the printer?

So what are the MFC settings? Presuming the server it is trying to get to is external?. It might indicate who provides the mail / SMTP and what is needed to get to it (or if you are now locked to the ISPs smtp all of a sudden to relay through)

I guess if you are allowed to run executables and so forth, BLAT with a GUI is an option.

It is a commandline mailer you can configure with the same details and a test message, that will feed back any server messages to console the printer is likely receiving.

Thanks for all your help! I will give this a shot and pass all the info on to our IT provider and I will post if we come up with a solution :)
