Email settings configuration in RStudio Connect

I did some changes in the configuration file after read this post:RSConnect Quickstart Issue - Mail Report
and is now working!

I add "StartTLS='never' " after the Port argument in the [SMTP] block and used "localhost" in "Host" argument.

E-mails are now beeing sent, but they go to directly to the trash. I don't know if this was expected but at least the e-mail is working.

I also had installed "postfix" in the server machine but i don't think this helped.

Anyway, thank you Cole.
