I have a Dell 2335DN. I downloaded Stunnel from www.stunnel.org
This is installed on any host machine on your network. You use stunnel to create a SSL connection between your printer and (in my case) gmail or google apps or whatever email service you have.
The following configuration works just find for gmail and google apps sent directly from my printer.
Step 1: Find out your ip address for your printer and type that in your browser. This pulls up the printers configuration panel which is much easier than inputting the settings in the small monocrhome window on the printer’s face:
Step 2: Go to “Email settings” in your printer configuration window. The SMTP server is the IP address for the machine that you installed stunnel on. Your printer will use your local machine and stunnel as a proxy to send your file via gmail.
Step 3: I use Port 259 for SMTP and 1109 for POP3 (same ip address for each server SMTP and POP3)
Step 4. Input your gmail username and password for both entries
Step 5. Select the authentication checkbox for SMTP and POP3
Step 6: Install and configure your stunnel config file. You can just copy and paste the following and it will work fine:
cert = stunnel.pem
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1
client = yes
connect = pop.gmail.com:995 [imaps] accept = 143
connect = imap.gmail.com:993 [ssmtp] accept = 259
connect = smtp.gmail.com:465
Save Config File and reload through right click on systray app.
You will also need to add it to your startup
