Hi did you tried with latest nightly build ?

No, I didn't. I think that the last stable version has been installed. But i am not sure. Our mail admin Christian Mack is currently in vacation. He is capable to install a new nightly build in our productive environment.

It may be related to 0005721 - you can test the workaround instead

Members of University of Konstanz also report that the content of an email is not accessible anymore once it has been moved into Sent (German "Gesendet") folder. Due to Bug 0005721 checked that the To header was set. So I think the moving/copying may have caused this error.

Btw: This is the email that has been moved to Sent folder:

Subject: Re: Libero

Can you provide eml ?

I already did (see posting 0016848). This little eml snippen is all i got when I opened the source code of the email in Sent folder.

Hi Markus,

I have imported the message in 0016848 and got no issue when moving in draft folder (SOGo latest nightly).
Maybe you can try to import and reproduce on demo.sogo.nu

Hi Sebastien

This seems to be fixed in the nightly Version 5.8.2 (@sogo-build.alinto.int 202305092258).
Therefore you can close this report.

Thank you Christian !

Sebastien
