Outgoing e-mail server on Android

Hello, please ensure that your operating systems are up-to-date. As of 04/24/19, all email sent from a Cox Email address must use TLS 1.0 security encryption or higher. As a result, Cox no longer supports sending email through email clients using SSL security encryption version 3.0 or older. SSL / TLS encrypts information from potential thieves as it is sent from one location to another, such as when sending email messages. Choosing to encrypt with SSL / TLS provides added security to email. -Kevin M. Cox Support Forum Moderator

TO KEVIN Moderator:

My Android device, SamSung 8 OS is up to date according to T-Mobile rep who is the store Manager and owns a Samsung.

My  SENT email from my device are getting stuck in the Outbox. (receiving email is fine)

Are these the correct settings?

INCOMING SERVER: IMAP.cox.net

SECURITY TYPE: SSL

PORT: 993

IMAP path prefix OPTIONAL

OUTGOING SERVER: smtp.cox.net

SECURITY TYPE: TLS 

PORT: 587 (I tired 487, 465,, too = no luck)

Same issue here. Outgoing email quit working on all android devices a few days ago. Changing to the new settings of TLS port 587 generates error "server does not support authentication" and outgoing email is dead. However, it seems to work when I'm on wifi at home. I've also seen the message that email will be sent when I have network connection again.... but I can browse the web just fine.

EDIT: Verified that gmail works without being on wifi, so it's just Cox having problems. That seems to rule out my phone carrier, and my phone email software as potential culprits. It may have something to do with the new security settings Cox seems to have put in place for outgoing email a few days ago.

YES it's set properly.

and I retyped my name and password
