Multiple bodies

[EtienneBruines]

Its often convenient to send both text/html and text/plain: pretty emails for those that support it, and basic emails for those that don't.

msg := gomail.NewMessage()

msg.SetBody("text/plain", "Hello!")
msg.SetBody("text/html", "<b>Hello!</b>")

However, the second SetBody, replaces the first.

I managed to fix this, by changing in gomail.go (lines 175+)

// SetBody sets the body of the message.
func (msg *Message) SetBody(contentType, body string) {
    msg.parts = []part{
        part{
            contentType: contentType,
            body:        bytes.NewBufferString(body),
        },
    }
}

to

// SetBody sets the body of the message.
func (msg *Message) SetBody(contentType, body string) {
    msg.parts = append(msg.parts, []part{
        part{
            contentType: contentType,
            body:        bytes.NewBufferString(body),
        },
    }...)
}

However, the name SetBody does not seem appropriate anymore. Perhaps this should be renamed to AddBody in this case (breaking change), or another function all together (SetBody with the original behavior, and AddBody with the new behavior. ) Or perhaps AppendBody instead of AddBody.

Any thoughts?

AddAlternative is exactly what you are looking for.

Did not see that one! Thank you.
