Hello,
strange it was working, than I did upgrade of SOGo and it stops (yes, I broke
rule do not fix what is working).
the working version was 5.5.1.20220408
now with broken pictures is 5.5.1.20220423
(upgrade sogo:amd64 5.5.1.20220408-1 5.5.1.20220423-1)
So something must changed in version 5.5.1.20220423 comparing to 5.5.1.20220408.
My configuration is little bit strange, I have web server (IIS 10) which is
mapped to public internet address using NAT, on this server is running reverse
proxy too,
pointing to internal mail server where nginx server with iRedmail +SOGo is
running (ubuntu 20).
on nginx is in sogo template
location ^~ /SOGo {
include /etc/nginx/templates/hsts.tmpl;
proxy_pass http://127.0.0.1:20000;
# forward user's IP address
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
# always use https
proxy_set_header x-webobjects-server-port $server_port;
proxy_set_header x-webobjects-server-name $host;
proxy_set_header x-webobjects-server-url https://$host:443;
proxy_set_header x-webobjects-server-protocol HTTP/1.0;
proxy_busy_buffers_size 64k;
proxy_buffers 8 64k;
proxy_buffer_size 64k;
}
with greetings
Daniel

I have do some investigation, and I have found that pictures in response
contains internal server ip, not the $host address, and because I use reverse
proxy, the picture address is wrong as visible from firefox network
comunication.

I see it also in source of mail

Somethink must change in SOGo, which probably ignores $host value in response
when setting img src url.
Make sure you properly add all the x-webobjects-server-* headers before passing
the requests to sogod. If you use Apache, check the recommended config:

After SOGo update with night build, it stops showing png -pictures in e-mail
body, instead it shows them as downloadable attachments at the page footer.
