Can no longer send roadrunner imap email from iphone ios 17.1.1
I can no longer send email on my roadrunner account from my phone- fine in and out from pc, can receive mail, but not send from the phone. RR tech support cannot help, nothing I have found on-line so far helps. I deleted the account from my phone and let ios add it back- again cannot send. Get error message outgoing server mail.twc.com is not responding.
Anyone know how to resolve this?
iPhone 13 mini, iOS 17
