Instalei recentemente o squirrelmail no servidor Ubuntu 18.04 seguindo principalmente as diretrizes emComo configurar um servidor de email no Ubuntu 18.04?
Consigo usar o login do navegador, mas ao tentar enviar e-mail, entro /var/lob/mail.log:

Estou um pouco confuso até mesmo sobre qual mail_userdeve ser o e-mail associado à conta, conforme defini no squirrelmail/config/conf.pldomínio papa-legba.ddns.net. Eu abri a porta para smtp.
