Can't send emails on android

[Luigi66]

Hi, I can receive emails and everything looks okay and I can do everything else. But I can't send emails says not connected  to server.

@Luigi66 -- a few questions:

1. which Android device?
2. which E-mail program?
3. what is the name of the E-mail server, e.g., "mail.shaw.ca" or "mail.telus.net" ?
4. is it connected to your home WiFi network, or connected to your cellular provider? (Shaw Mobile, Freedom Mobile, Telus, Rogers, Bell)
5. receiving E-mail requires you to send your E-mail ID and its password to the mail-server. So, this should always work, no matter how your device is connected to any Internet Provider.

1. Galaxy S9

2. shaw.ca

3. shaw.ca

4. on phone connected to Telus

5. I understand that, but it does not work! As far as I can see there is no reason that it should not work.

@Luigi66 -- I expect that Shaw will not allow any TELUS user to connect to Shaw's mail-server without any "authentication" -- spammers would love such an "open-relay" mail-server -- accepting E-mail from "anywhere" and delivering it to "anybody".

Are you using the settings that Shaw lists at:

   How To: Set up your Shaw email - Shaw Support

in order to "authenticate" yourself as a Shaw customer who is then entitled to connect to Shaw's mail-server?

Same problem on Galaxy AO3

@lspado -- same problem

Are you connected via WiFi to your cable-modem's WiFi network, or are you using "data" on your mobile-phone?

Have you configured the "outgoing mail server" to be "mail.shaw.ca" ?

On wifi receive okay but can't send  Galaxy AO3 android.

Configured as required

@lspado wrote On WiFi receive okay, but can't send Galaxy AO3 Android. 

Whether on WiFi or on "data", to receive E-mail, you must send both your ID and your password, to authenticate.  So, with that information, you will not have any problem receiving the messages.

If you configure E-mail on your device to connect to the mail-server provided by your cell-phone provider, and you are NOT using WiFi, can you send?  If you then disable "data" and enable WiFi, can you send?

In order to defeat spammers who try to send through mail-servers other than their ISP's, mail-servers are "picky":

1. if you are connected via WiFi to your cable-modem (on Shaw), you can send through Shaw's mail-server, because the mail-server recognizes that you are a Shaw customer;
2. if you disable WiFi, and enable "data", and then try to send through Shaw's mail-server, the mail-server will refuse to accept your outgoing messages, because your IP-address does NOT identify you as a Shaw customer.

E-mail programs can be configured to use "authenticate-before-sending".  Then, when you are connected via "data", you will send your Shaw ID and your password to authenticate, and the mail-server will allow you to send through it.

So, how is your E-mail configured for your "outgoing mail-server" setting ?
