clamscan is failing to move files from the maildir folder to a virus folder. I think this is due to the filenames containing characters such as = , : these names are automatically assigned by exim4 when putting the mail into the new directory and by courier when moving them. Can someone help with this? running debian sarge thank you clamscan: cannot move '...on,S=4357:2,ST' to '...tion,S=4357:2,ST': Invalid argument.
