Never seen this, but check Account -> Properties -> Transport, whether STARTTLS is selected under Connection in Send mail.

Hello,

Today I try to send an email and I received this error:

5.7.0 Must issue a STARTTLS command first

And the email is not send.

I´m using The Bat! Professional v11.4.3, POP3, with Windows 10 updated.


How can resolve this?

Thanks

Best regards
