Ah, /etc/freshclam.conf
But you'll need to create a custom template to make the changes.
cd /etc/e-smith/templates-custom/etc/
mkdir freshclam.conf
cd freshclam.conf
vi DatabaseMirror
Add:
DatabaseMirror your.closest.server.tld
DatabaseMirror db.local.clamav.net
DatabaseMirror database.clamav.net
ESC
:wq!
Reason you add the second and third entries is becasue they overwrite the originals. So for a failsafe, leave them in.
To finish up:
expand-templates /etc/freshclam.conf
To check if the entries are in:
cat /etc/freshclam.conf
Lastly
sv restart /service/freshclam
