Since about 2 weeks i have a problem viewing pictures in html-mails:
When i view the message in Thunderbird (Linux and Win 11), there is only a placeholder for the picture.
When i view this message in my Roundcube webmailer, all is fine an the picture is shown immediately.
At the moment i have no idea what’s going wrong, but because my users have the same problem it’s not so funny!
I really hope someone has an idea to solve this!
Thanks in advance,
