Re: Avoiding spam blacklists

Is your mailserver's external ip static or dynamic? I am afraid that mail servers from dynamic ips always get listed as spambots even when using SPF, DKIM, correct rDNS etc. The solutions in this case are either to get your isp to allocate to you a static ip (not all isps offer this however), set

Re: Avoiding spam blacklists

I'm on Digital Ocean, which is basically similar to Linode. You can just get a new IP and maybe have better luck. That is employ the "V" in VPS.  For a brief period you will be charged for two VPS. Digital Ocean charges by the hour (like a seedy motel). Probably Linode is similar. The reason
