I just recently upgraded mimedefang and I have run into problems, after few hours of work identified as wrong permisions on files passed for scanning.
But during the troubleshooting, I noticed that currently there is no checking for error returned by clamd in message_contains_virus_clamd function, only in entity_contains_virus_clamd. And even that one is not giving much information, just reports failure.
The attached patch adds more error reporting for easier diagnoists. Hope you find it useful.
Thanks
Tomas
