Alexandre,
Thanks for your answer.
I use Debian OS and see there is a backport package available for the
file utility.
So I’ve just upgraded from 5.11 to 5.17.
Is there a way to test, without asking and disturbing the original
poster to resend, and send the email present in my quarantine through
amavis filter ?
I usually use mini_sendmail for testing purposes:
http://acme.com/software/mini_sendmail/
It takes a complete mail (with header) on stdin,
and feeds it using SMTP to a specified host/port
to a recipient specified on a command line.
