MailClient implements a trivial SMTP client

func (*MailClient) SendMail

func (mc *MailClient) SendMail(to, from string, mail []byte) error

SendMail will send mail to "to" using "from" as sender. Mail must already correctly formatted since SendMail only takes care of SMTP. Errors returned signal if a retry might work.
