Re: [go-nuts] Read multiline error response from smtp.SendMail

[Dave Cheney]

What happens when you print the original text from err.Error() ?

Hi,

I am using this code:

err := smtp.SendMail(

smtpHostPort,

auth,

sender,

[]string{recipient},

[]byte(message),

)

if err != nil {

log.Printf("sendSmtp: failure: %q", strings.Split(err.Error(), "\n"))

}

However the multiline error response seems truncated:

2013/02/06 11:54:41 sendSmtp: failure: ["530 5.5.1 Authentication Required. Learn more at"]

How can I get the full multiline error response?

Thanks,

Everton

Pretty much the same:

//log.Printf("sendSmtp: failure: %q", strings.Split(err.Error(), "\n"))

log.Printf("sendSmtp: failure: (%s)", err.Error())

2013/02/07 18:40:40 sendSmtp: failure: (530 5.5.1 Authentication Required. Learn more at)

Sounds like the error message is truncated when it is generated. It
probably looks like this on the wire:

530 5.1.1 Authentication Required. Learn more at
530 5.1.1 tehsecures.derp.com. Alternatively you can
530 5.1.1 receive this error by dialing 9 on your touch
530 5.1.1 phone keypad.

I don't know how to fix this, or if it is valid RFC 821.

As far as I could trace from the source, smtp.SendMail eventually calls (indirectly) textproto.ReadResponse to read the multiline response.

Then textproto.ReadResponse is expected to return the full multiline response.

smtp.SendMail from: golang.org/src/pkg/net/smtp/smtp.go

textproto.ReadResponse from: golang.org/src/pkg/net/textproto/reader.go

May this be a bug?
