cvielma on "[Plugin: WP Mail SMTP] SMTP -> ERROR: Failed to connect to server: Connection refused (111)"

In my environment:
- WordPress 3.5.2
- WP-mail-SMTP 0.9.1
- WP-SMTP 1.1.5
- Hosted in GoDaddy

Through Settings -> WP-SMTP set:
From: my email ("asdf@gmail.com")
From Name: "Whatever you like"
Host: localhost
SMTP Secure: None
Port: 25
SMTP Authentication: No
All the other fields empty.

Then through Settings -> Email Set:
From email: (blank)
From name: "Whatever you like"
Send all WordPress emails via SMTP option selected
Encryption: No encryption
Authentication: No
All the other fields empty.

And that's it.

Specifically I was configuring it with Contact Forms 7 so, even when it didn't work for me, these pages gave me some guidance:
