Question about esf_skip_hosts

[twv]

I have easy spam fighter enabled. A client cannot receive emails from a vendor because the vendor uses zoho.com and the vendor’s domain does not have DKIM correctly configured. If I add *.zoho.com to /etc/virtual/esf_skip_hosts, will that fix the problem?

That might fix the problem. It's better that the remote server fixes ther DKIM or DNS problem, because it can also be that DKIM is correctly configured but their nameserver is not (I had that issue too). Or use esf_skip_ips if it's always the same ip.

You can also use whitelist options in /etc/virtual to accept mail in addition to the esf_skip_hosts file.

I agree with Richard it more the vendor's problem for not being compliant.
