Eu configurei um servidor de e-mail no Ubuntu.
Eu verifiquei as portas estão abertas e eu verifiquei todos os arquivos de configuração, verificando com cada resultado da pesquisa do Google que eu poderia encontrar. A maioria das postagens semelhantes tem registros e etapas mais complexas já realizadas.
Eu posso enviar e-mails do meu servidor sem problemas, mas não consigo recebê-los.
Aqui está o registro de e-mail depois de tentar receber um e-mail do meu e-mail da universidade e meu e-mail do gmail:

Seu mydestination não inclui seu próprio domínio, portanto, o Postfix não sabe se deseja entregar o e-mail localmente. É por isso que você vê erros como "Acesso de retransmissão negado" e "Retornos de email para mim mesmo".
Parece que você já configurou isso, mas comentou.
#mydestination = vapsterthekoala.com, makaveli, localhost.localdomain, localhost
mydestination = localhost
Basta adicionar seu nome de domínio a mydestination e recarregar o Postfix.
Eu não sei o que fiz de errado, mas refazer a configuração novamente consertou o problema. Um guia para quem estiver interessado. link
