Unable to send email from yahoo uk

I am unable to send email from my yahoo.co.uk email address. I can however receive emails to this address.
I have logged in to the webmail and I can send emails from there, so the problem must lie with EMClient.

I can send emails from other email accounts from the EMCLient, so the problem is specific to yahoo.

Hi mattk101

Yahoo require that all 3rd party email clients need a special key,
To generate this key go here and follow the instructions:

Thanks skybat.

I was already using an app password. I have just removed the account and then added it again, it’s working now. I’ve no idea why!
