Secure SMTP

Hi, I want to send e-mails using the gmail smtp server. I understand that google only accepts secure connections. Is it possible to use SendMail to do this?

Re: Secure SMTP

you need to use stunnel (or something like that) to redirect your mail through it

cheers,

Esteban

Hi Sebastian,

Hi, I want to send e-mails using the gmail smtp server. I understand that google only accepts secure connections. Is it possible to use SendMail to do this?

As Esteban mentioned on getitmade.com we're doing precisely that - using our google account to send the mail. Here's our configuration:

1) You need to add WAEmailConfiguration as a configuration ancestor.
And you need to add this configuration:

SMTP Server = localhost
SMTP Port = 259
SMTP Server user name = <your account, for example [hidden email]>
SMTP Server password = <your account password>

2) You send mails with this string:

GRPlatform current
seasideDeliverEmailMessage: ((WAEmailMessage
from: (WAEmailAddress address: '[hidden email]')
to: (WAEmailAddress address: '[hidden email]')
subject: 'test')
body: (WAStringEmailBody string: 'a test')).

it works inside the application (inside a session)... not outside (see below)

3) You need an stunnel installed and running. In ubuntu, you need to change:

a) replace stunnel.conf with:

client = yes
debug = debug

[smtps]
accept = 127.0.0.1:259
connect = smtp.gmail.com:465

b) create /etc/stunnel/stunnel.pem

openssl req -new -x509 -days 3650 -nodes -out stunnel.pem -keyout stunnel.pem

c) enable running:

/etc/init.d/stunnel4

ENABLED=1

/etc/default/stunnel4

ENABLED=1

d) restart:

sudo /etc/init.d/stunnel4 restart

If you want to send the mail outside the session for example on a service task you need a mock request context then use something like:

WACurrentRequestContext

use: IZMockCurrentRequestContext

during: [

GRPlatform current

seasideDeliverEmailMessage: ((WAEmailMessage

from: (WAEmailAddress address: '[hidden email]')

to: (WAEmailAddress address: toEmailAddress)

subject: aSubject)

body: (WAStringEmailBody string: aBody)) ]

You'll also need at least version SMTPMail-NickAger.9 you can grab it from the attachment on this bug report http://code.google.com/p/glassdb/issues/detail?id=248 (I don't have permission to check it into the repository ... anyone)

Re: Secure SMTP

Just be even more explicit:

1) You need to add WAEmailConfiguration as a configuration ancestor.
And you need to add this configuration:

SMTP Server = localhost
SMTP Port = 259
SMTP Server user name = <your account, for example [hidden email]>
SMTP Server password = <your account password>

In code this would read something like:

app configuration addParent: WAEmailConfiguration instance.

app

preferenceAt: #smtpServer put: 'localhost';

preferenceAt: #smtpPort put: 259;

preferenceAt: #smtpUsername put: '[hidden email]';

preferenceAt: #smtpPassword put: 'Rea11yS3cur3'. "that isn't our password!"

Hi, thanks for your help.

I created the tunnel with Stunnel as Esteban suggested, and it works out when sending e-mails from Pharo but not from Gemstone. What is strange is that if I send an email debugging the code, the connection succeeds and the e-mail is sent, but, if I do it by evaluating the code, it fails.

I am testing it by evaluating this:

| client server mail username password|

    username := '[hidden email]'.
    password := 'xxxx'.
    client := SendMail new.
    client user: username.
    client password: password.
    server := 'smtp.lalala.com'.
    client
        mailhostName: server;
        smtpPort: 5000;
        [hidden email]' ;
        to: '[hidden email]';
        subject: 'From Gemstone through Stunnel';
        text: 'It works!'.
    client send

Note: I have loaded SMTPMail-NickAger.9.mcz

Any idea about what could be happening?

Re: Secure SMTP

I still have this problem connecting to the tunnel. Are you using it successfully?

On debugging "SendMail >> send" message I have notice this:

openTcpConnection
| ok |
ok := self connectTo: self smtpPort on: self mailhostName.
ok ifFalse: [self close].
^ok

This method answers true only when I am debugging. Running the code in only one step answers false.

Internally this method calls to #_twoArgPrim: opcode with: arg1 with: arg2

with opcode = 2 arg1 = hostname arg2 = smtpPort

and returns nil

Any help may be of use

thanks!

Sebastian
