Good day,
I installed iRedmail 1.6.4 on a clean Ubuntu server 22.04.3-amd64, made all the settings (similar to installing iRedmail 1.6.3), but the size of attachments to the letter through the SOGo interface does not change.
Limit 1Mb. The 1.2 MB file already gives an error.
I checked the settings according to the manual.
Without changes.
In iRedMail 1.6.3 with the same settings, everything works on Ubuntu 20.04.6.
Tell me where else to look?

The question is closed. The reason was the reverse proxy. Completely forgot about him. I corrected the config and everything worked.
