    Question Turning off AV & Spam filters?

    Hi all,

    I did a search of this in the forums and noticed a few posts, but mostly for older versions of Zimbra.

    We have a Barracuda spam/AV appliance that scans everything coming into our email box. Is there any danger in disabling these in Zimbra? Would turning these off add any speed to the server (thinking the less it has to do, the better).

    Thanks,
    Rob

    Default

    I'd leave them on-extra insurance.
    -i might set the time it checks for clamav updates higher-like 24hrs or something
    -and just turn off any outside real time blacklists if you have any

    zmprov gacf | grep zimbraMtaRestriction to see what RBLs are set.

    I'm not talking about:
    reject_invalid_hostname
    reject_non_fqdn_hostname
    reject_non_fqdn_sender

    I'm talking about the outside spam list checks-which take the most time, resources, and bandwidth:
    reject_rbl_client dnsbl.njabl.org
    reject_rbl_client cbl.abuseat.org
    reject_rbl_client bl.spamcop.net
    reject_rbl_client dnsbl.sorbs.net
    reject_rbl_client sbl.spamhaus.org
    reject_rbl_client relays.mail-abuse.org
