| duas observação para marinheiros de primeira viagem: | |
| 1 . na linha: | |
| default from: “remetente” | |
| se você não usar um email valido no lugar do ‘remetente’ ele vai gerar o erro: | |
| “Net::SMTPSyntaxError in UsersController#create 504 5.5.2 : Sender address rejected: need fully-qualified address” #em development |
Prereq:
apt-get install zsh
apt-get install git-coreGetting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh
wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh
