Problems with SMTP

Hi all,

For some reason using an authenticated SMTP I manage to send emails through my HP MFP machines, but when I use authenticated SMTP it always fails.

Any idea why this might be happening?

PS: The authentication username and password are 100% correct.

Thank you all

Removed black formatting and deleted duplicatepost.

This is a highly specific to HP gear. I'd check HP's support site or call them about it.

However, there are some posts in the HP Support forums, such as this:

https://h30434.www3.hp.com/t5/Scanning-Faxing-Copying/smtp-authenticated-on-hp-printer-website-but-not-on-printer/m-p/8833192

If all that fails, I'd consider doing a packet trace to see what you could learn.

The OP is not using an email program. (S)he's using a printer.

................... using an authenticated SMTP I manage to send emails................but when I use authenticated SMTP it always fails.

That sentence doesn't make sense.

If everything works fine when you use a server that doesn't require authentication then why is that a problem for you?

I hope I've understood what you're trying to say.

The problem is that whenever we are using SMTP without authentication its getting us blacklisted!

Ah, I see.

In the "Summary and Test" section of your last screenshot, it shows everything's OK yet displays the error "The operation failed". What operation and why did it fail? Without a proper error message it's going to be difficult to offer a fix and I'll just be playing guessing games.

Are you sure the username is in the correct format? Perhaps it should be just "office1.printer".

I thought I was going to see aproblem with SMPT but now I am comfused. I would like to learn about the funtion of SMPT in email set up of Thunderbird (Mozilla). as an email handler. Can someone guide me to this topic ?
