Can't send email
I switched off each and every protection setting I can find. (newbie alert)
In AV I switched of scanning incoming and outgoing emails.
I whitelisted my email client (The Bat!)
I can receive emails but not send them. Sending just times out after a while.
The email server (Gmail) is fine because I can send from my phone and web browser using te same account without any issues.
EDIT: Perhaps related; I get a lot of DNS errors when surfing on the PC with BD 2018. Others PCs in my network don't have any issues.
