Como corrigir o login do usuário Dovecot para usar o e-mail de domínio completo neste formato "[email protected]" [duplicado]

Eu configurei o dovecot e o postfix... O servidor de e-mail funciona bem.. (Webmail e Outlook funcionam..) Eu criei usuários usando o comando unix..

usreadd -s /sbin/nologin myuser

Mas tenho uma preocupação, se quiser fazer login no webmail ou no Outlook, tenho que usar myuser em vez de [email protected].

Por enquanto estou usando, apenas nome de usuário como abaixo..

Se eu usar [email protected], ele diz que é um usuário inválido, tanto o webmail quanto o Outlook.

Eu tentei pesquisar no Google .. sem sorte .. ainda .. por favor, alguém por favor me dê uma luz ..
