Email wont send

Without warning or change emails wont send when using EM client. If I access my account provider (BT) directly it is fine. Therefore seems to be a problem with EM client software. Emails received fine. Help requested.

Hi Glen,
which version of eM Client are you running?
Can you try to send an email and then check the Tools > Operations window for any errors in the Error tab and copy the contents of Log tab (in the same Operations window)?

Best regards,
