can't send spectrum/roadrunner email using AT&T internet

We're happy to look into this for you, @johna27502.

What error message do you get when you try to send email from your Spectrum account?

Have you reached out to their customer support to make sure that your email account is still active after switching providers?

I'm having the same problem.  I'd like to send email using my roadrunner email  @austin.rr.com using the ATT server since that's what the WIFI i'm connecting to is.  I thought I could send any email but i'm not sure why it's rejecting it.

Hey @RobAustin1159,

We are here to help with your inquiry about using your own Email server.

1. You will need to make sure that your server is not running on port 25. Check our AT&T Network Practices. Skip down to "What practices has AT&T adopted to manage network security?" We have disabled port 25 due to malicious and spam content that runs on that port.
   • Here you can also see if your Email server violates any of our terms of service.
2. You will need to check third party blacklist website to see if your Email has been reported.
   • You will need to get your Email removed from their site first. 
   • We take information from the blacklist websites to help secure our network from potential malicious users.
     • If yours is listed and there is a mistake, and you have gotten them to remove it. Please Email our postmasters with the issue. They will send you a list of instructions, and information needed to get your Email removed from the block list.

Let us know if this helps.

Hi @RobAustin1159, we are happy to help.

Please help us understand you request. Are you stating that your @austin.rr.com email is not working on AT&T internet service?

What error message are you receiving?  Are you using a mail client for you emails?

Please let we know how we can better help with your issue.

I've also noticed that when attempting to send Spectrum RoadRunner email on my AT&T phone internet that I get error reaching server greeting message. I'm using AquaMail on a Note 10+ as I have for years. Nothing has changed except for the recent sending mail error. I believe that some blocks of AT&T mobile ip addresses may be blocked by Spectrum as spam. As soon as I turn on wifi and connect the mail will send just fine. It should be noted that 3 other email addresses, with 3 different email providers, work just fine on either wifi or AT&T mobile internet...just not the Spectrum RoadRunner email (which is why I think it's a IP Block issue). Would you, AT&T, please check with Spectrum for mobile internet IP address blocks?

I am having the same issue.  as long as I am connected to my Spectrum wifi, I can send emails using my ****.@austin.rr.com just fine from my iPhone.  As soon as I am off my spectrum wifi, I still receive emails, but I cannot send.  This is a problem.  The email settings are correct.  I am using port 587 for outgoing mail.  

error message on iPhone when on AT&T 5G network:

cannot connect to outgoing mail server for 

*****@austin.rr.com

Omg, why doesn't AT&T  help us? Here it is: we cant send email unless we are on wifi (doesn't matter what wifi). If we are on Our mobile AT&T network it wont send. Why????

Similar to johna27502, I performed a trace route on my iPhone.  

see the results below.  When on spectrum wifi, you can see it going through spectrum addresses.

Nobody seems to care. 
I just went ahead and cancelled my AT&T service and went back to spectrum. 
good luck!!

I've been on the phone all day today.  Twice with Spectrum, once with Apple, once with AT&T.  Spectrum and Apple point to AT&T.  AT&T claims it's Spectrum.  This is complete nonsense. 

It has to be AT&T.  It works fine when I'm on Spectrum wifi.  It does NOT work when I'm on AT&T network.  

It's Spectrum, they have a blocks of At&t's mobile network identified as spam, so that's why Spectrum won't allow it. That's also why it works regardless of what wifi you are on. At& and Spectrum need to get together to unblock those ip blocks.

Hello ...  Has anyone figured out how to fix this problem ?  Like others, outbound RoadRunner mail does not go on the AT&T Network.  WiFi is fine.  Thanks.

Yes,

I fixed it by staying with Spectrum and cancelling AT&T.
