TWC has linked to my laptop twice, changed my email settings to mail.twc.com from pop-server.roadrunner.com, POP, 25 and 110, full email address, tried 587 and 993 ports (plus a few I can't remember), removed account and then added as new, they changed accounts to IMAP,  disconnected modem, router, computer, with authentication and without, with secure SSL checked and without, all with no change.  Receiving, but not sending on all five email addresses of Roadrunner.com.  GMail imported to Live works and will send.  Mail will send from TWC roadrunner mail page.  Using IE, no other issues, no changes before this stopped sending last week.  Error message below.

An unknown error has occurred.

Subject ''
Server Error: 421
Server Response: 421 dnvrco-cmomta02 cmsmtp ESMTP server temporarily not available AUP#2300
Server: 'mail.twc.com'
Windows Live Mail Error ID: 0x800CCC67
Protocol: SMTP
Port: 25
Secure(SSL): No

Any ideas what else I could try?  I have not had a problem before this, no new programs, no downloads, ran virus scan and malware -OK.  Avast is turned off now, no change, no prior issue. I don't want to log in to each separate email through TWC webpage and want my email back to what it was!  I only use my laptop for browsing and email, not knowledgeable about computers at all.

Thanks for any help you can offer.
