@Luigi66 -- a few questions:
1. Galaxy S9
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:
in order to "authenticate" yourself as a Shaw customer who is then entitled to connect to Shaw's mail-server?
@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" ?
@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":
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 ?
