My outgoing settings are wrong. The port is wrong and Use SSL to connect (recommended) When I try to send an email, it bounces back and says "We couldn't deliver your message" and has this info: SmtpSubmissionPermanent5XXException: Smtp submission failed. Server 'smtp.cox.net' Port '587'. --> Unexpected SMTP server response. Expected: 250, actual: 503, whole response: 503 not available Failure code: be0 I can't figure out how to change the settings. There's no setting I can find to do this. McAfee screen comes up white Whenever I try to access the McAfee Internet Security screen it only comes up as a white screen. I tried uninstalling it (white screen again) and doing a system restore and an earlier version restore but no luck. It seems to be working but I can't access it. Any ideas? I'm running Win7 64 bit.
