Unable to scan and email on Dell 1355cnw
I am having an issue with emailing scanned images from a Dell 1355cnw color printer.
First off, this has worked before.
But ever since an extended power outage due to Hurricane Irma, it has not.
Through the use of various tools like Wireshark , Thunderbird, and an SMTP emulator that I have written, I have concluded there are no problems with my ISP, router (firewall), or Road Runner’s SMTP email service. FYI, I tried this against smtp-server. tampabay.rr.com, mail.twc.com, and my own SMTP emulator.
I’m 100% sure my login credentials are correct. DNS and paths to WAN servers are correct, SMTP ports are correct.
In laymen’s terms, here is what I would expect…
Printer opens a connection to Road Runner (RR) SMTP service
RR says "Hello"
Printer says "Hello"
RR says "I can help you, but I will need some login info. Are you ready to provide that?"
Printer says "I'm ready"
RR says "What is your account?"
Printer says "My account is …"
RR says "What is your password?"
Printer says "My password is ..."
RR says "OK, I trust you, what do you want to do"
Printer says "Send the following email ..."
RR says "OK, I completed that, what's next?"
Printer says "Goodbye"
RR Disconnects.
I captured the protocols by using Thunderbird. Then I used putty to log into Road Runner, passing encoded account and password information.
I developed an emulator to respond to SMTP service requests as Road Runner would.
I used putty once again to verify my SMTP emulator works as Road Runner’s SMTP service does.
I pointed the printer to my emulator and captured the session with Wireshark
So here is what is happening…
Printer opens connection to Road Runner
RR says "Hello"
Printer says "Hello"
RR says "I can help you, but I will need some login info. Are you ready to provide that?"
Printer disconnects
This sequence repeats itself over and over.
Only way to stop it is to specify a bogus SMTP gateway that won’t resolve.
I've upgraded the firmware on the printer to the latest.
Anybody have any thoughts?

The printer is out of warranty and Dell wants bucks to talk to them.
Here is a more detailed description of communications between printer and SMTP server.
Again, I am having an issue with emailing scanned images from a Dell 1355cnw color printer.
Thiis has worked before….
Not sure if RoadRunner (aka TWC & Spectrum) changed something in the last few months
Through the use of various tools like Putty, Wireshark , Thunderbird, and an SMTP emulator that I have written in perl, I have concluded there are no problems with the ISP, router (firewall), or Road Runner’s SMTP email service. I tried this against smtp-server. tampabay.rr.com, mail.twc.com, and my own SMTP emulator.
I’m 100% sure my login credentials are correct. DNS and paths to WAN servers are correct, SMTP ports are correct.
Here is what I see when emulating an SMTP client session to mail.twc.com using putty.
I connect with putty connection type “raw” on port 587
TWC sends
220 Welcome to Road Runner. WARNING: *** FOR AUTHORIZED USE ONLY! ***
I send
EHLO there
TWC sends
250-dnvrco-cmomta03 hello [1.2.3.4], pleased to meet you
250-HELP
250-AUTH LOGIN PLAIN
250-SIZE 30000000
250-ENHANCEDSTATUSCODES
250-8BITMIME
250-STARTTLS
250 OK
I send
AUTH LOGIN
TWC sends
334 VXNlcm5hbWU6
I send
My encoded account name
TWC sends
334 UGFzc3dvcmQ6
I send
My encoded password
TWC sends
235 2.7.0 ... authentication succeeded
I send
MAIL FROM:myaccount@tampabay.rr.com
TWC sends
250 2.1.0 sender ok
I send
RCPT TO:
TWC sends
250 2.1.5 recipient ok
I send
DATA
TWC sends
354 OK
I send
From: "Me" < myaccount @tampabay.rr.com>
To: "You" < myaccount @gmail.com>
Date: Tue, 17 October 2017 11:06:00 -0500
Subject: Test message
A simple test message
.
TWC sends
250 2.0.0 uniquieID mail accepted for delivery
I send
QUIT
TWC initiates disconnect.
This works perfectly - I receive message at my gmail account.
Based on the above session, I developed an emulator to respond to SMTP service requests as TWC would.
I used putty once again to verify my SMTP server emulator works as the TWC’s SMTP service does.
I pointed the printer to my emulator and captured the session with Wireshark
So here is what is happening with the printer trying to connect with TWC (or my emulator).
I setup email alerts and a paper fault condition on the printer.
Printer opens connection to my emulator on port 587
My emulator responds with
220 Welcome to Road Runner. WARNING: *** FOR AUTHORIZED USE ONLY! ***
Printer says
EHLO iptarget
My emulator responds with
250-dnvrco-cmomta03 hello [x.x.x.x], pleased to meet you
250-HELP
250-AUTH LOGIN PLAIN
250-SIZE 30000000
250-ENHANCEDSTATUSCODES
250-8BITMIME
250-STARTTLS
250 OK
Printer initiates disconnect.
I assume this is the same problem when I point the printer to TWC. I am not onsite where the printer is and cannot sniff out the exchange between the printer and TWC>
I've upgraded the firmware on the printer to the latest from Dell’s support site.
I realize the printer doesn’t support SSL and I see TWC is sending a STARTTLS.
But using putty with TWC, I’ve shown that an unencrypted session works fine with mail.twc.com.
I’ve set the printer’s Email Send Authentication to SMTP AUTH (AUTO), Plain, Login, and even Invalid.
I can only think that there is something in the EHLO response that is missing or might have changed that the printer doesn’t like. In my emulator, I eliminated some of those 250- type commands to no avail.
Please, anybody have any thoughts?
