Hi Maurizio, I have tried this configuration with both versions you mentioned as well as with the current git head. I wasn't able to reproduce this behavior on any of them.
Giiven that, I will need some additional information: 1. What version of Debian you are using? 2. How did you install mailutils? If compiled from source, please send me the resulting config.log file. If installed via apt, what repository did you use (AFAIK, Debian still ships version 3.10). 3. What tool did you use to connect to imap4d? Regards, Sergey
