Hi,
I’m back on this subject after a few monthes. Sorry for the delay in responding.
To answer Klaus question, I haven’t noticed any error message in logs.
The thing is that i was able to reproduce this error on 1.8.004. I made a fresh install from scratch on a fresh ubuntu 12.04 server install and I still cannot attach files from filemanager while generating an email.
I can see that the files are attached in the email but it is not sent.
Attaching local files from my computer works properly.
Is there something I forgot to install on my server?
