Weird issue with SMTP mailing address

I set up a gmail notifier. It is trying to send the email, but is adding “email/” to the email address. Am I missing something? Here is my notify

  - name: gmail_paul
    platform: smtp
    port: 587
    timeout: 15
    sender: !secret notificationemail
    encryption: starttls
    username: !secret notificationemail
    password: !secret gmailpassword
      - !secret pauls_secret_email
      - !secret pauls_secret_sms
    sender_name: The House

I see a failed to send email in the senders inbox with the following message

Your message wasn't delivered to email/[email protected] because the address couldn't be found, or is unable to receive mail. 

I don’t have email/ in my secrets. Just wondering if anyone has seen anything similiar

No problems with smtp for me.

I have the following setup:

  - platform: smtp
    name: gmail_smtp
    starttls: true
    port: 587
    sender_name: Home Assistant
    sender: !secret smtp_sender
    recipient: !secret smtp_recipient
    username: !secret smtp_user
    password: !secret smtp_password

and in secrets.yaml

smtp_recipient: [ [email protected], [email protected] ]

Maybe it helps.

Good deal, I might try putting my two recepients as a single line
