Issue sending mails when away from home on iPhone

Email uses connections to 2 mail servers, one for incoming and the other for outgoing mail. It sounds like the outgoing mail server (“SMTP” server) is not configured correctly. The most common error is not providing a user ID and password for the outgoing server when setting up the email account. It is slightly confusing because those fields are labeled “optional”, but they are only optional if you don’t want to send mail. It works at home because the Spectrum mail server knows you are a “trusted” user because you are logged in to their Wi-Fi network. When you are away from home you are not using their Wi-Fi, so it doesn’t “trust” you.

Enough for the explanation; here’s how to fix it:

The easiest way is to delete the Spectrum email account, then set it up again following the guidance on their website for iPhone setup. Go to Settings/Mail/Accounts and tap on the account to manage it.

You can also go to the same place, tap on the account, then tap on Outgoing (SMTP) server and entering your email ID and password.

For years, With my MacBook Pro and phones, we have had no trouble at all with a Spectrum mail account at home, on the road, even in Europe. So, there goes the theory about everything being Apple's fault.

Spectrum says it is Apple's problem.

Of course, but they are wrong. Whoever you spoke to at Spectrum needs more training. What do you think Apple will say if you ask Apple Support?

I see Lawrence Finch has already answered, so we'll leave the details to him.

I have tried the above.

I am continuing to receive emails on my iPad, but not send.

My iPad Incoming Mail Server Hostname setting is mail.twc.com.

The Outgoing setting is the same.

Thanks for your assistance
