Is there a way to set up an email account for sending only?
I have a mail server that I used just for relaying SMTP. It seems with the settings you need to configure accounts that connect to IMAP or POP just to send email.
Even If I choose “disable SMTP authentication”, the email account settings force a user/password or choose “waiting for password”.
Perhaps I just need to go into Postfix configuration and add my SMTP relay service then use localhost???
