SOLVED Verizon vtext.com is blocking messages

[JIKOmetrix]

Hello,

My smarthost for outbound email is having an issue with Verizon. Their infrastructure IP's have been caught in large blocks issues by Version. I can no longer use my cell phone [mycell number]@vtext.com to email to text for notices.

We acknowledge the current situation with outbound mail being bounced to the domain vtext.com (Verizon email to text) due to an apparent real time and/or block rule on their mail servers. We have contacted multiple channels into Verizon but we are getting no status, feedback or updates. As for our mail, we believe it to be clean and without knowing the cause from the Verizon vtext.com use acceptance policy block we cannot investigate further. Verizon has put a static block on large swaths of IP address space including ours which leaves us with no avenue to mitigate within our infrastructure. Furthermore, we have found on some community forums that Verizon may have, or are in the process of, changing their email to text policy and is NOT accepting non-enterprise connections.
We recommend customers implement the following workaround to allow the vtext.com mail to be sent directly from your mail servers (bypass the GoSecure Email Gateway). Below are steps for Microsoft Exchange and Exchange Online. For other mail server platforms, you may need to reach out to their support for similar steps to accomplish this workaround.

So want to send all my server domain mail to the smarthost except I want vtext.com recipients to be handled as local distribution not smarthost.

Any I idea on how to do this in cpanel exim advanced editor?

I know I could get another smarthost like mailgun or something since you can setup more that one smarthost "vtext.com 192.168.0.1", "* outbound.example.com" , however

However, I try this I get either invalid data requirements smarthost will not be updated or SMTP services won't send email.

Any thoughts on how to split this up so vtext.com sends from local server?

Try setting up a static route?

Exim config to route email to certain domains through another provider?

Hi folks, There's a regional bank with which a ton of people in our area do business. We route all our mail out through SpamExperts. The bank has a rule on their Barracuda ESS that prohibits any mail from a non-US IP address from being delivered to their accounts. I have tried numerous times...

Thank you. I'll try this today.

Hello,

When I try to use the localhost for delivery I get this error:

SMTP Error (451): Failed to add recipient "[email protected]" (Temporary local problem - please try later).

If I set to different smarthost, then it will send.

Within the confines of WHM's editor, I think you can use a static route.

Code:
static_route:
driver = manualroute
transport = remote_smtp
route_data = ${lookup{$domain}partial-lsearch{/etc/staticroutes}}
Then in /etc/staticroutes you specify your route.

vtext.com: SMARTHOST_IP

You put this after the POSTMAILCOUNT section.

See: EXIM relay only if recipient is at hotmail.com for more info.

Hello,

After more testing, the only way I could get the above to work is to use a second host that is the local server.

Thanks.
