write: broken pipe

[arundudeemmt]

when using gomail it works fine in first go but after hour which is like default timeout of smtp servers, if email is sent then a following error is thrown : gomail: could not send email 1: write tcp XXXXXXXX:8807->YYYYYYYYYYY:25: write: broken pipe

Looked at code but seems we are checking io.eof error only and we do dial again but there in other cases error is not handled .

func (c *smtpSender) Send(from string, to []string, msg io.WriterTo) error {
if err := c.Mail(from); err != nil {
if err == io.EOF {
// This is probably due to a timeout, so reconnect and try again.
sc, derr := c.d.Dial()
if derr == nil {
if s, ok := sc.(*smtpSender); ok {
*c = *s
return c.Send(from, to, msg)
}
}
}
return err
}
IMO we need to do sc, derr := c.d.Dial() in other error conditions too .
