Can't send Comcast email on iPhone

I'm no expert, but after digging around ANYWHERE I possibly could to resolve the very same problem you had, I stumbled across a solution:

I went into Settings, Mail/Contacts/Calendars, Accounts-Comcast-Mail, Outgoing Mail Server-SMTP, Primary Server-smtp.comcast.net and then merely retyped my password. My iPhone 5s's e-mail system worked immediately.

Hope this helps.

New problem: my password in that second location keeps getting deleted.

Sometimes I can get it to "stick" and I can send emails all day. Sometimes it gets erased as soon as I hit ENTER.

What can I do to make it stop being erased?

help!

Details:

Running OS X El Capitan, 10.11.6, using Comcast email.

"Outgoing mail server (SMTP)" / "Edit SMTP server list" / (type password) / "Enter" (or push, 'return').

Go back to email and hit "send". Get error message again, "cannot verify password".

Go back to Mail / Preferences / etc. and find the password that I had just typed in has been erased.

Sometimes this can go on a half a dozen times until it finally works and doesn't get erased when I hit "send".

*** is erasing it? Very frustrated. Help!

Hey bithedz,

Thanks for the question. It sounds like your Outgoing Mail Server is configured incorrectly. To change these settings, you’ll want to navigate to the following:

1. Tap Settings > Mail, Contacts, Calendars.

2. Tap the Mail account for which you would like to change the settings. If you configured your account using any of the built-in presets, IMAP, or Exchange, you may need to tap Account Info on the following screen.

3. On the Account Info screen, locate the Outgoing Mail Server section and tap the existing SMTP entry. A list of SMTP servers will appear with the Primary Server and Other SMTP Servers.

via iOS: Configuring additional outgoing mail servers

From here, choose your Primary Server, and change the “username@smtp.comcast.net” to the correct entry (usually just your username, without the @comcast.net, then your password).

Thanks,

Matt M.

Thx Anxiousbeachbum! I had a similar issue with my Comcast email just now and your solution helped immensely!! Much appreciated!

Thank you Anxiousbeachbum. Same issue, same difficulty finding a solution...until your post. 🙂

Incredible. That's all it took for me to... just retype the password. GRRR! I've had this problem for sooooo looooong!

Many thanks for posting this. I realize that the original question is a bit old now, but the issue is still out there. I've been going from mildly annoyed to off the wall annoyed between Comcast customer service and hunting on line for a solution. Tried what you suggested here and my email now sends like a champ!!

Thanks for this info. I have spent nearly a half day trying to fix this. I tried removing and re-adding my Comcast account several times, to no avail. For some reason it's either not taking, or using some default password under the SMTP settings. The incoming works just fine, as I was receiving emails, but all my outgoing email was sitting in the Outbox.

When you create a new account It doesn't prompt you for this, but it's really a two step process: 1. Enter the IMAP password, 2. Enter the same password again under SMTP password settings.

You would think when you are prompted for the initial password that it SHOULD populate both password fields, but apparently it is not, and this should be fixed. And long overdue, from the looks of it!
