Sending email notification from share the modified email logo is missing




I have a problem with my email templates when im sharing a file.
I changed the default email logo, and if i send the test mail to my network there is no problem, but if i send to outside the net to gmail or another mail address, the logo is not visible.


I searched the forum, and maybe there is some certificate problem with my server but im not a pro in this.

Thanks for the help!
