hello Debian group

but it's this possible that clamav-daemon use 1.2G memory?

Entirely possible. As I recall, clamav-daemon caches the virus definitions in RAM in order to minimise startup speed when handling clients.

In other words, if you're only scanning for viruses occasionally (e.g. mails which have an attachment), you might find switching from "clamdscan" to "clamscan" and not running the daemon suits your purpose.

try to punish little without getting any negative effects.

try to enclose, but after 4-5h the mailserver will freez/break

Depending on your system architecture, you could consider running "clamdaemon" on a different host, and configuring "clamdscan" to use a TCP socket. This is particularly beneficial if you have several hosts which need to perform scanning as they can all pass their payload to the central scanning host, and you don't need multiple instances of the daemon.

YMMV.
