![]() ![]() Sometimes you can get the ip off the list, sometimes not. They'll just refuse the ip - end of story. Your configuration or domain won't matter. One day I would hope blocklists would become a little more discerning than just blanket ip range banning regardless of what domain or sender is using it.ĭescription Many places block ip addresses associated with vps providers. If you have just a volume of mail like under 100,000 a month, it may be easier and more time efficient to use an smtp provider for your email service. Some places will accept mail from your IPv4 but block it if you connect with the IPv6. Try to keep all mail routed on your IPv4 address. That is even harder to get mail accepted with. It would be a small miracle to get an ip on a vps that didn't get refused in some places.Īlso be careful about using the IPv6 address. Some will even just silently discard your email. I would recommend getting email accounts or test to friends on several providers and see if your email is getting delivered. Apple, Comcast, ATT, and Microsoft all come to mind from my personal experience. Other providers generally are also in the same boat or worse.Įven ip's that you check and are clear of public block lists, are still blocked on other private ones. Getting a different ip may help but it's not very likely. ![]() Many places block ip addresses associated with vps providers. Until that happens, I'm afraid you are SOL. Most likely, the block will disappear just as mysteriously after awhile. My guess is that your TLD (.xyz) probably has something to do with this but only PP knows for sure. ![]() You can contact them using their website and try to get them to rehabilitate your IP address manually. PP is a subscription service so your email is prevented from being delivered to all PP subscribers (although, I've heard that there are tiers to PPs service…and the lower tiers will let some low-risk, bad-rep email through). Proofpoint uses some proprietary "AI tools" (marketing-speak for "uninformed, heavy-handed, & arbitrary decision-making", IMHO) to assign your IP address a "reputation score" and then blocks email from your address if the score you get assigned isn't up to snuff. Welcome to the internet! The problem most likely doesn't have anything to do with your server. My guess is that your TLD (*.xyz*) probably has something to do with this but only PP knows for sure. PP is a subscription service so your email is prevented from being delivered to all PP subscribers (although, I've heard that there are tiers to PPs service.and the lower tiers will let some low-risk, bad-rep email through). Also set up the other two ports while I was testing (548 and 80) and had the same issue.Welcome to the internet! The problem most likely doesn't have anything to do with your server. I created a set of Port Forwarding rules for UDP 500, 1701, 4500, and 10000. Or is it the Peplink? It's running the latest firmware. So is it Comcast? They say the modem is in Bridge mode (and because I can get online with the public static IP I am inclined to believe them) and should be passing all traffic through (but of course I have no way of verifying that, and Comcast tech support can be hit or miss). I can ping the firewall after turning that option on so i know I can get a response. Now it could certainly be my setup as I've not used PepLink before (we just happened to have one in the office on the shelf), but given the issue is the same across two different brands of firewall, I'm curious. I recreated all the firewall rules, but given the age of the Sonicwal, I chalked it up to the firewall having issues and configured a PepLink Balance 20 with the same basic setup (pass the L2TP VPN traffic through to the internal server, along with AFP and web forwarding for testing purposes). Īnyway, after switching the public IP on the firewall, we had no issues with getting online, but it turned out the external access (VPN and a few other test services) couldn't be accessed. He assured me that everything was going to remain the same after the move as before ("You're sure they will let you keep the same IP address?" "Yes, I specifically asked them that") but of course it changed, meanwhile Comcast can't ever pull up the new account without looking by the static IP assigned. ![]()
