Cannot send mail (SMTP) on MacBook using Spectrum
I have a mail.twc.com (Spectrum) email account and I use my mac mail program to manage my mail. When I am at home I can receive my mail and send my mail with no problems. When I am away from home with my Macbook Pro I can receive mail but I can't send it. I went to preferences and checked through all my setting and everything is set up correctly. However, on my outgoing mail it shows as mail.twc.com (offline). I'm sure this is the problem but I can't get the offline off. I have no problem when sending mail with my iPhone. I have duplicated the setting on my Mac same as on my iPhone. Suggestions?
