Avatar in email notification.

[budman1758]

Hello. I use an email notification when my watering system runs. The notification has been working quite well. I am curious about one thing though. In the header of the message there is an image and I wonder where it comes from. See the picture attached.

I have no idea where that particular image comes from. There are no image files showing up on the file browser of the unit. It's not any avatar I use anywhere. How would one go about changing it?

It is connected to an account at your email provider? And what email client is used? That might try to find the avatar 'intelligently'

I use SMTP2go and I just searched all over that account and can't find a single thing about an avatar in the account.
Also just searched through all settings for bud@catmakanic.com and found nothing.

BTW, this unit is an ESP32. Are there any plans to support encryption for email notifications?

Could it be a cache issue of your email application?
Or a hash function collision, where some association of a cached file is somehow the same hash value for some other string.

Years ago I had something similar, where a company logo of someone I know was somehow shown as avatar for someone else.

I have no clue how to prove or disprove that.....lol

Clear cache of the browser, but that often also clears logged in sessions.
So you could try to look at it using a different browser, or on a different computer/device.

By the way, the image looks like the avatar of a user here on the forum.

Same thing on two different machines and browsers.

I was thinking the same thing...... Weird.

Found it. Somehow that avatar was attached to MY name in the contacts list. No idea how or when that happened. The contact list was imported into Roundcube from an export from my phone. That avatar was also on the contact (of me) on my phone.

Problem solved. Still no idea how I got that particular picture in the first place.......

Ah, we keep amazing ourselves

Yep that makes sense....
Like I said, it happened to me once with contacts on my phone.
I think the (Android?) hashing algorith may be prone to has collisions (as is any hash function), but then doesn't detect the collision and acts on it.
