 Posted: Sun Jul 26, 2009 5:49 pm Post subject: SMTP with AUTH support |
 |
|
Hello,
is there any plan of implementing support for SMTP AUTH in MLDonkey? I'd like to be able to use the GMail SMTP server to send e-mails...
I know that I should be more collaborative, and try to learn Ocaml, but I don't know anything of functional languages (I'm proficient in Java, Tcl, C, C++)....
Thanks a lot |

|
|
Hi spiralvoice and other respected people from this forum.
I have no right to demand to write that either. But can I ask and beg   .
This function is very, very helpful, but in my opinion, the work for its implementation will require not a lot.
Or am I deluding myself strongly in the simplicity of the implementation of this function, or a lot of people think that there is something complicated, and because such a small thing, not yet written.
Below, I announced the results of my cursory look at the implementation of this.
File is responsible for sending mail is | Code: | | mldonkey\src\utils\net\mailer.ml |
, as I understand it.
I have studied features of the protocol SMTP (not all of course  ) and I can responsibly say that our common goals, we do not need something grand.
I personally conducted the session via Telnet to the mail server, and passed authentication, sent a letter directly from the telnet interface. The only thing that was difficult was the need to recode the username and password to Base64.
In our case (as it is now working in MLdonkey) without authentication - the process is different in that the exchange with the server, we do not send a command to authentication, such as
AUTH LOGIN
And do not send the username and password, respectively, everything else is done in exactly the same (!).
Below I give a piece of code where in my opinion, lacking just a few lines of code (well, of course, still need a code to pick up parameters from the settings).
-----mldonkey\src\utils\net\mailer.ml ------------->>>
begin from string number 139:
| Code: | let sendmail smtp_server smtp_port new_style mail =
(* a completely synchronous function (BUG) *)
try
let s = simple_connect smtp_server smtp_port in
let ic = in_channel_of_descr s in
let oc = out_channel_of_descr s in
try
if read_response ic <> 220 then bad_response ();
Printf.fprintf oc "HELO %s\r\n" (gethostname ()); flush oc;
if read_response ic <> 250 then bad_response (); |
#####################################
############ HERE should be the code that sends the parameters prescribed in the username and password.
I'll describe how I understand it, note I do not know the syntax and all, "both my hands were left". #####################
##############My example################
| Code: | Printf.fprintf oc "AUTH LOGIN" (); flush oc;
if read_response ic <> 334 then bad_response ();
Printf.fprintf oc "name_on_mail_server_auth_base64" (); flush oc;
if read_response ic <> 334 then bad_response ();
Printf.fprintf oc "password_for_name_on_mail_server_auth_base64" (); flush oc;
if read_response ic <> 235 then bad_response ();
|
#########
Warning: it is not patch, only my personal view as it possible realizable
#############################################
| Code: |
if new_style then
Printf.fprintf oc "MAIL FROM:<s>\r\n" (canon_addr mail.mail_from)
else
Printf.fprintf oc "MAIL FROM:%s\r\n" (canon_addr mail.mail_from);
flush oc;
if read_response ic <> 250 then bad_response ();
if new_style then
Printf.fprintf oc "RCPT TO:<s>\r\n" (canon_addr mail.mail_to)
else
Printf.fprintf oc "RCPT TO:%s\r\n" (canon_addr mail.mail_to);
flush oc;
if read_response ic <> 250 then bad_response ();
Printf.fprintf oc "DATA\r\n"; flush oc;
if read_response ic <> 354 then bad_response ();
let body = make_mail mail new_style in
Printf.fprintf oc "%s\r\n.\r\n" body; flush oc;
if read_response ic <> 250 then bad_response ();
Printf.fprintf oc "QUIT\r\n"; flush oc;
if read_response ic <221>
Printf.fprintf oc "QUIT\r\n"; flush oc;
if read_response ic <> 221 then bad_response ();
close_out oc;
raise e |
P.S. Either I'm naive and there, something must be difficult to pile up, or all those who thought that the opportunity to write this - thought that there is something unreal.

Yes, it is that simple. Note that SMTP servers may support different kinds of authentication, not only PLAIN as in your code. Also many servers nowadays are using SSL as a transport layer (for good). But I think we can start supporting simple cases and then evolve as necessary.

Patch implementing SMTP authentication (LOGIN, PLAIN and CRAM-MD5 methods) was committed.

What i do wrong ?
Hello. Thank you for your work in this direction, it is very necessary.
But maybe I did something wrong and I do understand.
I prescribe these settings:
Then press Enter and all is lost, as I understand is stored in the configuration.
But then, nothing happens. I prescribe the correct smtp server, password and email, but I do not priohodit no notification of the completion of injection and not at all.
How to check where the error?
How to configure? (Maybe I'll even write an article on the wiki on this topic)
As for the logs to track exactly where he stumbles work?

Most probably you need my instead of my@mail.example (this depends on server configuration). If it doesn't work - show the strace output when it sends mail, i,e. strace -f -s1024 -ttT -p $(pgrep mlnet) -e '!gettimeofday,poll'.

Enter the new value for smtp_login, press Enter.
Enter the new value for smtp_password, press Enter.
When changing option values in HTML interface it is necessary
to press Enter for each change.

Yes, it helped. Now it works. Will need further clarification in the inscription below.
Help:
| Quote: | | !! press ENTER to send changes to core!! |
need add:
for each value.
ygrek, and how can you do to notice a few people came? I tried a comma does not work.
And will work for almost every individual user, because the properties of each created user can add e-mail address.
Maybe it's the tracker record as request features?
P.s. For the current implementation, a separate and thank you very much
