I just took on a customer. They are running sbs2003 server w/exchange and an out of date Sonicwall. One account is getting massive amounts of spam and I'm worried that they will eat up all the named properties. I need to buy myself a few weeks until mgmt starts spending money on upgrading ect.. How do I identify and temporarily fix this issue with the least customer disruption?

They must update sonicwall and enable some basic anti-spam filters like DNSBL and REV

I tried to activate the spam trial and got this message:
Connection Failure

SSL negotiation with the license manager server has failed. This could be caused by an incorrect date/time setting on your firewall.
System time is SUN JAN 04 14:21:05 2015 . You may go to System > Time to adjust your time.

How do I fix it?

Your time might be correct. Your Time Zone might be wrong.
Follow the system's directions: System>Time.
Usually you can do that pointing your browser to the SonicWall's IP address.

You must upgrade firmware to have new RootCA-s and 2k long server key support.

In system->Time the time is correct and the time zone is correct. I made sure the device is using a NIST NTP Server.

It's 10:04AM in System Time. but the message I get says

System time is SUN JAN 04 15:03:42 2015 . You may go to System > Time to adjust your time.

Makes no sense

I upgraded the firmware and activated the anti-spam trial. I've never done sonicwall and to enable the anti-spam trial they are asking me to remove existing rules at firewall->access rules.  It is a mail server aiutodetect failed. It mentions a wizard but I don't see it

DNSBL does not require licence.
content-based spam filters are heavy
