Twitter emails being blocked

Something is very strange, teach525.  I use my gmail account on twitter so always get email from them.  As a test, I tried to change my email to my cox.net account.  Twitter took the change and said it sent confirming email to my account ... nothing received.  I changed it back to gmail an immediately received a confirming email in my gmail account.  Something is happening to email sent from Twitter to a cox.net account   My spamblocker is set to "Deliver junk email to the WebMail Spam folder for later review." and the twitter mail is not in any folder, checked them all.

Hopefully, a Mod can help getting this fixed.  In the meantime, a work-a-round is to use a gmail or other web based email account but that won't help you with a password reset.  Maybe contacting twitter support will help.

Same issue here last night, Twitter sends the link to change passwords and nothing shows up in my cox.net account.

Even getting stranger the more I test.  I have both twitter.com and verify@twitter.com white-listed on the "Allow and Block Messages" settings, did not help, still nothing when I try to change my twitter email to cox.net.  Now, I have a private domain that redirects email to my cox.net account.  I changed my twitter email to that account and volia, the e-mail came through.  So, can't get email to a cox.net account but can get it when sent to an account redirected to cox.net.  Major difference is:
- when changed to cox.net account the Received from is spring-chicken-av.twitter.com
- when redirected the Received from shows a Godaddy (registrar for my domain) server and the spring-chicken server is father down the Received from list.

Mods, if you want copies of the email headers to help solve this issue, please let me know, thanks.

I can't tell, Becky, as I am unable to successfully change my twitter email to Cox.  I make the change but can't get the email with the link to confirm it ... email stays at the previous until the new is confirmed.

We know of 2 functions are not working:
- teach525 and seymor posted change/reset password email from password@twitter.com
- I have found change email address email from verify@twitter.com

both are sent from a server like spring-chicken-ax.twitter.com

Thanks Becky, I'm glad you were able to duplicate the issue.

Hi Becky,

Any update on this? I have the same problem and I'm locked out of my Twitter account because of it. I have no way to verify my identity or reset my password because my Cox email address won't receive any messages from Twitter Support. Gmail has no issue whatsoever. This is incredibly frustrating. 

I am having (as well as others) the SAME problems.  Cox is apparently as of 8/8/2016 blocking email-forwarding from GoDaddy servers that goes to my cox.net email address.

To work around the problem for now, I had to change GoDaddy to forward my email to myemail@yahoo.com account, and then have my Yahoo account forward copies of all emails received to myemail@cox.net account.  NOT ACCEPTABLE long term.  

Please fix!  See thread here:

Hi Electricaesthetic,

Our network security team has unblocked several IPs that were identified as Twitter mail servers, but attempts to change my Twitter account email address still failed. The team is still investigating. I'm sorry for the delay!

I'm grateful for the investigation, but anxious for a resolution. Please keep me updated. Being permanently locked out of a social media account I use for my small business will be extremely harmful.

Hi John,

Unfortunately I don't know if this solution works for those of us not using GoDaddy; from my perspective, the Twitter blocking isn't an issue in email forwarding but rather a complete message rejection from the Cox servers. You can't forward what your ISP never receives in the first place. I'm frankly very concerned about the fact that Cox has decided to completely erase these messages instead of marking them as spam for review. It makes me wonder what other potentially important correspondence I've missed if Cox's firewall is arbitrarily blocking reputable IP addresses. 

The blocking from GoDaddy (maybe also Twitter and other?) seems to be fixed now by Cox.  I am starting to get emails originally sent from Monday and Tuesday, so looks like Cox is reprocessing them and accepting them again and finally delivering them.  The emails were never bounced, they just just disappeared.  Now they are appearing again.

Still can't get an email from twitter.  Tried again to change my email from gmail to cox.net and no confirmation came through.  When I tried changing it to a private domain email redirected by godaddy to Cox, the confirm came through almost immediately.  Still nothing received on the one's sent directly to Cox.net.  Same result Becky reported yesterday and I had on 1-Aug

Confirming that Cox is still blocking Twitter's emails. If I'd known about this problem, I never would have registered the account with my cox email address. Any news from the investigative side of things, Becky? I'm hoping for a prompt resolution. 

Any update on this?
