No cliente web do Gmail Settings -> Accounts and Import, eu

1. adicionado [email protected]para Check mail from other accounts:extrair dados via POP; e-mail recebido é rotulado
2. adicionado [email protected]para Send mail as:poder enviar e-mails como [email protected]

Quando um terceiro envia um e-mail para [email protected] e eu tento responder no Gmail, ele define [email protected] como destinatário, em vez do terceiro que enviou o e-mail.

Como garantir que Replya função preencha Too campo com o destinatário correto? Espero poder enviar uma resposta de [email protected] para terceiros.

O que exatamente acontece quando instalamos um debpacote que acaba como uma instalação quebrada e como apt-get -fremediar a situação (em vez de isso acontecer durante a instalação para começar)?

Exemplo:

1) instalamos o pacote ferdi baixado de https://github.com/getferdi/ferdi/releases/tag/v5.3.3 :

$ dpkg -i ferdi.deb
Selecting previously unselected package ferdi.
(Reading database ... 180829 files and directories currently installed.)
Preparing to unpack .../ferdi_5.3.3_amd64.deb ...
Unpacking ferdi (5.3.3-157) ...
dpkg: dependency problems prevent configuration of ferdi:
 ferdi depends on gconf2; however:
  Package gconf2 is not installed.
 ferdi depends on gconf-service; however:
  Package gconf-service is not installed.
 ferdi depends on libappindicator1; however:
  Package libappindicator1 is not installed.

dpkg: error processing package ferdi (--install):
 dependency problems - leaving unconfigured
Processing triggers for mime-support (3.64) ...
Processing triggers for hicolor-icon-theme (0.17-2) ...
Errors were encountered while processing:
 ferdi

Como podemos ver, o pacote não está instalado corretamente devido à falta de dependências.

2) No entanto, consertar o pacote quebrado é bem-sucedido com facilidade:

$ apt-get --fix-broken --yes install

1. por que as dependências ausentes não são instaladas durante dpkg -i?
2. por que é apt-get -fcapaz de resolvê-lo facilmente?
3. isso é uma coisa boa a se fazer ou pode levar a um sistema quebrado?
