## Email
I needed a way to send email from a [Ponzu](https://ponzu-cms.org) installation
running on all kinds of systems without shelling out. `sendmail` or `postfix` et
al are not standard on all systems, and I didn't want to force users to add API
keys from a third-party just to send something like an account recovery email.
### Usage:
`$ go get github.com/nilslice/email`
```go
package main
import (
"fmt"
"github.com/nilslice/email"
)
func main() {
msg := email.Message{
To: "you@server.name", // do not add < > or name in quotes
From: "me@server.name", // do not add < > or name in quotes
Subject: "A simple email",
Body: "Plain text email body. HTML not yet supported, but send a PR!",
}
err := msg.Send()
if err != nil {
fmt.Println(err)
}
}
```
### Under the hood
`email` looks at a `Message`'s `To` field, splits the string on the @ symbol and
issues an MX lookup to find the mail exchange server(s). Then it iterates over
all the possibilities in combination with commonly used SMTP ports for non-SSL
clients: `25, 2525, & 587`
It stops once it has an active client connected to a mail server and sends the
initial information, the message, and then closes the connection.
Currently, this doesn't support any additional headers or `To` field formatting
(the recipient's email must be the only string `To` takes). Although these would
be fairly strightforward to implement, I don't need them yet.. so feel free to
contribute anything you find useful.
#### Warning
Be cautious of how often you run this locally or in testing, as it's quite
likely your IP will be blocked/blacklisted if it is not already.
