Aloha !
 
I am trying to set up a white list for a domain. Craigslist - it is always ending up in the junk folder. legitimate responses to ads we have placed, even the verifications when we post an ad, they all end up in the junk folder.
 
I went into white list on the Security tab, and the only thing it offers is to white list an IP address or IP range. That's not useful.
 
So how do I white list the domain itself ?

Why do you want to whitelist an entire domain?  Whitelisting anything is extremely dangerous!

Hi Curtis.  I agree with Bruce.  Whitelisting an entire domain is basically allowing them unfettered access through your SmarterMail server.  If you simply want to stop their messages from being treated as spam, you'd be better off adding them as a Trusted Sender.

Whitelisting is not on a domain.  It is on the SMTP servers that transport mail for that domain.  You need to find the IP addresses that Craiglist uses, and whitelist them.  I wouldn't do it, but that's what you asked.
 
Note that if you could whitelist a domain, then any spammer could simple spoof a Craigslist address and put all the spam they want in your inboxes.  Don't think your users would be too happy with that.

Thanks guys.
Rod, I did what you suggested and put them in as a Trusted Sender. That is what I was trying to do, stop them from being treated as spam.
 
Regarding whitelisting a domain as bad... True, but whitelisting an IP address then is even worse !  If you whitelist a domain, then anything from that domain comes through, but as its set up now, you have to whitelist an IP address. Meaning "BillyJo-JimBob" web hosting service has 4,000 domains on it and all of them share the same IP address as a mail server.  all 4,000 could spam you and they get through if you whitelist that one IP.  I would much rather take the chance with a single domain than an IP address.
