I'll just add my complaint to the pile. This started for me 10/9/17. I have always been able to send with my roadrunner address in gmail. I can still receive roadrunner emails in gmail but can't send. I tried changing the settings in gmail but I get rejected. I can log directly into my roadrunner account on the spectrum page.
What options had you selected. I was able to do this using a test account.
If you delete the account first then select "Send Mail As" then Add another email
You can alter where it says name to whatever you like
Email address needs the entire address. Example JohnDOE@twc.com
Leave Treat as an Alias checked then click Next Step
SMTP is : mail.twc.com Port 587
Password: webmail password
leave checked secured connection using TLS
leave unchecked SSL
then click Add account.
It will send a email to the one you are adding with a confirmation code.
Type that in and click verify
You can change your default email to your TWC address if you like or leave
the default as Gmail. You can also decide if you want your replys to come from
the address they sent to, Gmail for Gmail and TWC for TWC or all from the same.
For mine when I am composing my email I use the drop down to select what
address I am sending from. I have 3 emails in my Gmail set up. I just have to
remember to change it to the one I want to send from.
Hope this helps.
