[Misc] SMTP Authentication causes error

[jonmdci]

I have been working on this issue for over a day now. We installed a MPC6004to replace a MPC5503. On both machines I am unable to get scan to email to work if SMTP Authentication is on. Customer uses gmail and I set up the gmail smtp server on port 465 (I have tried 587 as well. No change). I entered a valid gmail account and password but whenever I attempt to scan to email I get the error "Authentication with the destination has failed". I have logged into the gmail account successfully so the password is correct. I have also tried using other smtp servers with authentication and all have the same error. The 5503 is now at my office and connected to my network and is having the same issues and there is nothing on the network side blocking anything. It seems like it must be a setting on the copiers that is the issue but neither I nor my service manager can seem to figure it out.

I just turned off authentication and tried using my smtp server on port 25 and this works, but when i turned authentication back on the error reappears.

I am an IT guy not a tech but as I stated, I have been working with the service techs and manager and we are all thoroughly stumped.

Any help or even just new ideas would be greatly appreciated.

The gmail account turn on less secure apps.

I'm sorry. I forgot to mention that before but less secure devices is enabled on the gmail account. I have set up dozens of copiers using gmail and that was always the only issue. This is something else. Thanks for replying tho.

The only thing I can say that is a problem, and I've seen it before, The IT setup a machine and he swore that it was the machine. I check the settings and he has the email address as @google.com, instead of @gmail.com. So I would verify again that you have a valid email and PW.

And this was a guy that was in the business a long time.

Can Auth be set to STARTTLS? (req'd for port 587)

Try to remove Verify Server Certificate check box if any.

From what I understand, Google has been trying to do away with support for "less secure device" since before the start of the year. You might try the following from Google support. Send email from a printer, scanner, or app - Google Workspace Admin Help

I NEVER enable less secure Apps...it's just not a good idea to reduce the level of security
I enable 2FA, and create an App Password to use to authenticate the device(s).
That's the ONLY way it will work once 2FA is enabled.
Never had an issue.

Screen shot please

Re: SMTP Authentication causes error

set the second dns to 8.8.8.8

If the machine is in any kind of Active Directory domain network, do NOT do this.

Very true, but sometimes knowing what NOT to do is just as important, especially if it can avert disaster.

Thats true like turning on Smb1 like some techs suggest.

However No solution is not what the tech is asking for help wants or needs.

Double check DNS settings


Again a screenshot would help

For the record, rthonpm has given me about 100 pieces of advice and he's batting .1000 so far. He's explained to me before why not to use a pubic DNS server in this situation but I forget why at the moment.
