Email send problem PC MS Outlook from .nc.rr.com email

I have newly installed ATT fiber; prior was Spectrum cable; no problems with ATT Internet - speed/connectivity spot-on

I use @nc.rr.com email - owned by Spectrum

Prior to getting ATT Internet I had no problems SENDING email from PC Outlook 2010 client and I could receive also

Now connected to ATT I cannot SEND (but can still receive) email

Same issue on iPhone 11 sending from @nc.rr.com mail acct

However, if I disable WiFi on iPhone and try via cellular data I have no problem

I have tried both POP3/SMTP and IMAP/SMTP Outlook client - no difference

Error reported by Outlook:

Task '[email scrubbed] - Sending' reported error (0x800CCC6F) : 'Your outgoing (SMTP) e-mail server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).  The server responded: 554 p-impout002.msg.pkvw.co.charter.net cmsmtp 68.89.xx.yy blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1130'

Note: 68.89.xx.yy is my public ATT IP

The Spectrum email-error-code site says error AUP#Out-1130 is:

The IP address you’re trying to connect from has an issue with the Domain Name System. Spectrum requires a full circle DNS for emails to be allowed through. Verify the IP you’re connecting from, and check the IP address to ensure a reverse DNS entry exists for the IP. If the IP address is a Spectrum-provided email address, contact us.

So far contacting Spectrum and ATT has resulted in a finger pointing circle of 2

Anyone have an idea how to resolve this?

The only thing I can think of is power cycling (turn off/on) your modem hoping that you'll get a different IP address that isn't blocked by Spectrum outgoing mail servers.

I posted this same question on the Spectrum user's forum and got this answer:

AUP#Out-1130 is an Acceptable Use Policy violation. Simply put, there is an issue with the IP address 68.89.xx.xx. The issue is usually that the IP address has been reported or identified for spam, or the reverse DNS record is incorrect or missing. Since you do not get the error on Spectrum internet, then your Spectrum services and email are working correctly. You identified that IP 68.89.xx.xx is an AT&T address, so only AT&T would be able to address the issue with the IP address.

So if an ATT employee is monitoring this thread I'd like a comment from ATT

This is a customer-to-customer forum and any AT&T employees who wander by probably won't be able to help you.

You can input the full IP address here to see if it's on any known blocklists although I believe AT&T also has their own list which isn't on this web site....

I'd be surprised if AT&T was handing out IP addresses to it's customers that it was actively blocking, though.  However, AT&T continually surprises me by doing dumb things.

Spectrum mail server is blocking AT&T IP they think is "bad". Rebooting the modem may be the quickest way to solve the problem (if it's dynamic IP) or wait forever for AT&T to fix the "bad IP".

Duh, good point, @ptwmson isn't using the AT&T SMTP server.  But that should fix the problem....change Outlook and other devices to use AT&T's server.

However, there's no way the user is going to get a new IP address by any action on their part.  These are "sticky" IPs and about the only thing I've seen that will change the IP is cancelling service and re-ordering or buying a block of static IPs.

Rebooting your AT&T is 99.44% likely to do nothing to alter your IP address.  They are incredibly sticky.  AT&T is not all that interested in a third-party's opinion of the reputation of the IP addresses that it hands out to its customers.  

In your shoes, I would first try to find out what RBL or other adverse reputation sites are listing your IP address such that RR doesn't trust it. We can't do this for you because you've [very reasonably] masked two octets of your IP address.  Once you know that, we can go from there.

Yeah, it works and is actually the preferred way to avoid getting your outgoing mail stuffed into the spam boxes at places like Gmail.  They see you using some other server, one that you aren't physically connected to, and they immediately think spammer.

Thanks to all who have responded.  The 'sticky-ip' is probably associated with the MAC address of the ATT modem/router.  I'll try ATT support again and see about a new modem.

Unmasked ATT IP is: 68.89.70.157 and it's a /22 block

Yeah, that IP is on two popular block lists.  You should be able to contact both lists and ask for them to remove it.  That could take a few days, though.

Oh, and forget swapping gateways....that's not going to change the IP.

Yeah, technically your IP really belongs on SORBS DUHL because it is "officially" dynamic.  If you are authenticating to RR's mail server, they shouldn't hold you being on that black list against you.
