Client: read server response on DATA command

[kayrus]

Usually remote SMTP servers return a successful 250 code with an informative message, e.g. Queued %messageID%
Unfortunately current implementation doesn't allow to intercept this response, though it's required for message tracking and monitoring.

go-smtp/client.go

Lines 460 to 467 in 608f3c2

	_, _, err := d.c.Text.ReadResponse(250)
	if err != nil {
	if protoErr, ok := err.(*textproto.Error); ok {
	return toSMTPErr(protoErr)
	}
	return err
	}
	return nil
