Email will only send via wifi

[GKP26]

Have noticed lately that emails will not send from outbox unless via home WiFi.

Incoming emails are received as normal.

Settings seem ok.

Using Email app.

Just get message back saying Sending Failed.

Any help or suggestions ?

Heads up that the TalkTalk Test Mail is not going to respond more than once. It's not set up for multiple responses to the same mailbox.

If you wish to test your mailbox functionality then do a self-send message. Compose and send your own mailbox a message to see it go into the Sent folder without any send error message and see it arrive in and stay in the Inbox.

The Samsung app is not set up to use secure mail for the Incoming server. The port must be 993 and Security type SSL. Other than that all is good.

But do check and upgrade the password if it may be deemed as weak.  I recommend 12 - 15 characters (the absolute minimum is 8 characters) multicase letters and at least one number and one approved symbol.

The phone is a Samsung 

Email App details and Server Settings as attached.

The Send error message will have a description and a TT three digit error code. For example, "Cannot send the message" (TT401). Knowing the TT code will help to identify what's wrong.

Also tell us what the device is and what the Operating system version is and the Email app. Screenshots of the incoming and outgoing server settings are always helpful and if you'd image edit to obscure just the first part of your email address before uploading here using the picture icon above this Reply area.

Thanks.
