How do I relay email through Verizon

I'm trying to send outbound email from a mail server I host at home. It's my understanding that I can relay my outgoing email if I authenticate to the Verizon mail server. I've tried multiple times but always get: Server error: '550 5.7.1 Unable to relay'

Can anyone tell me how to do this? Depending on where you look it up, some sites say I have to go to outgoing.verizon.net, others say I have to go to smtp.verizon.net. Some say I need to use port 25, others port 465 or 587. I've tried all of these combinations with no luck. All the posts about this I can find seem pretty old.

You can only "relay" as your Verizon email id. What are you trying to do?

Current settings are at http://www.verizon.com/emailsettings

Essstially

SMTP to smtp.verizon.net port 476 using SSL

POP to pop.verizon.net port 995 usins SSL

I don't think it's the case you can only relay mail using your Verizon email address. It's my understanding that you can host your own email domain and server as long as you authenticate to the Verizon SMTP server to send outbound mail. That's what I'm trying to figure out how to do.

A few things are important to know.

Verizon dynamic ip addresses are all blacklisted on the spam hosts.

Verizon only blocks outbound port 25.

You don't have to authenticate with them unless your hosting email servers behind a dynamic ip.

So knowing that. If you are hosting behind a static ip then the field is clear just avoid port 25.

If your dynamic then you'll find your ip on sorbs, spamhaus and other blacklists. That means you have to use "someone" to relay from.

Relaying means you are using their server settings.

If you use verizon then your pop settings are whatever your domain host settings are. Your smtp settings are described above but using your verizon I'd and pw to authenticate.

If your domain host has set settings then you can use them as long as you don't use port 25.

Right, the "someone" I'm planning to use for a relay is Verizon, but when I try I get "Server error: '550 5.7.1 Unable to relay.'" Since my outbound email would be through the Verizon mail server, it shouldn't get marked as spam beause their server isn't on the Sorbs list -- only the dynamic IP address ranges for residential use are. Verizon tech support has told me what I'm trying to do is a supported configuration but I haven't been successful. I suspect I might be using the wrong port, but mail server to mail server communication is normally done over port 25.

if you're doing port 25, then yes you're using the wrong port

So use this config

smtp.verizon.net

My server requires authentication (not the same as SPA, spa stays unchecked)

Your VZ User name and Password (make sure they are good by signing in at www.verizon.net)

Port 465 and use SSL

I am able to switch the port to 465, but Exchange doesn't seem to allow me to require SSL. I can require TLS, but haven't found a way to require SSL. If I use port 465 and TLS I still get "Server error: '550 5.7.1 Unable to relay.'"
