Hello,
When I send a mail via the latest version of RoundCube.
The recipient not receive sometimes the message. The message left the server, I can see that with the log
After investigations, we have constated that that's happen when the recipient use qmailscanner.
There is an error : Disallowed characters found in MIME headers
Is there a way to correct that ?
Thanks,
Christian,
