haha yeah really don't try to downgrade! make sure you've actually got the antispam/antivirus stuff turned on, then if that's still not working well for you start by reading the spam articles in the advanced bit of the wiki - wiki.zimbra.com. the default install is quite conservative with the spam filters - you can do lots of tweaking to improve it, i would guestimate my tweaked installs catch around 99.5% of all spam and viruses. |
