OK. It seems that more and more spam is getting through on our server. I'm assuming the spammers are getting better. It seems many emails are just text with a hyperlink now and have a score under 1.
I'm not sure how much training spam does. How long does this take to really have the zimbra server learn ?
Does everyone just use the builtin clamav for anti-spam? It seems in the last 3 weeks the amount of spam getting through has gone up. Has anyone else seen this? The only other thing I can think of doing is to lower the percentages for the anti-spam options.
Anyone have any ideas?
