Re: charter.net is blocking all Digital Ocean droplet email

by Kevin Stratton

I am not sure if this is off topic, but there were quite a few pay email services a while ago. I use https:/www.fastmail.com for the freedoom to switch ISPs without affecting email. They do support Thunderbird if you use an application specific password. Depending on your bandwith/storage usage, this might be an acceptable solution.

Re: charter.net is blocking all Digital Ocean droplet email

by Steven Greenberg

For at least a dozen years I have had my own website on GoDaddy. I also use my GoDaddy email as my main email route. (Although Thunderbird is getting ungodly slow of late as an email client.) I never want to be dependent on "free" email services like gmail. I am willing to pay a service like GoDaddy, so that places like Google and Facebook can't dictate what I can do just because they provide their services for "free". Charter did not start out to be a computer service provider. That's probably why I don't want to depend on Charter for computer services more than I have to. At the moment, Charter is the only reasonable service of internet connection to my house. /Steve On 2/12/2019 9:24 PM, John Stoffel via WLUG wrote: > > I need to vent here.

charter.net is blocking all Digital Ocean droplet email

by John Stoffel

I need to vent here. Charter.net which provides my internet, sucks. They are now refusing to accept email from *any* IP blocks owned by Digital Ocean, even though I've got a good mail setup on a droplet there, with proper DNS entries, SPF, etc. So I'm looking to spin up a new instance on some other provider, or I'm going to try and route the email via my @charter.net account that I have since I'm a customer. And I have opened a ticket with them. No answer. Jerks. What do people think of Vultr.com? Seems pretty comparable... I just wonder when Charter will block their IP blocks... Jerks. I think it's too expensive to buy an IPv4 address for more permanent use, since it's too easy for that block of 256 to be blanket banned by some jerks. Grr!!!!! John
