TLS Connection can't be established (not gmail)

[airsoft]

i'm having problems connecting to my an SMTP Server using TLS:

this is my code:

require_once "Swift/lib/Swift.php";
require_once "Swift/lib/Swift/Connection/SMTP.php";
 
$log = Swift_LogContainer::getLog();
$log->setLogLevel(Swift_Log::LOG_EVERYTHING);
$log->setMaxSize(200);
 
try {
        $smtp = new Swift_Connection_SMTP("smtp.unibe.ch", 587, Swift_Connection_SMTP::ENC_TLS);
        $smtp->setUsername("user");
        $smtp->setpassword("pass");
 
        $swift = new Swift($smtp);
 
        $message = new Swift_Message("test", "Test");
 
        $swift->send($message, "rcpt@mail.com", "sender@mail.com");
} catch (Swift_ConnectionException $e) {
        echo "There was a problem communicating with SMTP: " . $e->getMessage();
} catch (Swift_Message_MimeException $e) {
        echo "There was an unexpected problem building the email:" . $e->getMessage();
}
 
echo $log->dump(true);
 

This is the output of the script (with logging):

There was a problem communicating with SMTP: The SMTP connection failed to start [tls://smtp.unibe.ch:587]: fsockopen returned Error Number 0 and Error String ''

the port is likely to be correct (can connect to it with telnet)

phpinfo shows that php is compiled with OpenSSL 0.9.8g

furthermore it is possible for me to connect to that server via TLS with the following command from
the shell of the same machine as the script above is running on:

openssl s_client -starttls smtp -crlf -connect smtp.unibe.ch:25
 

Can somebody give me a hint to what i'm doing wrong?

Thanks in advance,

I am having the same exact problem. Did you find a solution?

My code is identical to yours and getting same error. I am able to use the test files - Smoke/TestConfiguration and send the test mails successfully to gmail on port 465. But putting in our mail.actifi.com server and login/port gives me the same error you are getting.

It sounds as though this server doesn't take connections with TLS at connection-time, but actually requires STARTTLS. Swift version 3 does not support STARTTLS since it was not possible at the time due to PHP limitations. There's a subtle difference between establishing a connection using TLS and using STARTTLS within a connection.

With the former Swift simply initiates the connection with TLS enabled.
With STARTTLS the client (Swift) has to connection unencrypted and then "switch" to TLS whilst remaining connected. This switching wasn't possible to do when I wrote version 3.

Ok, thanks.

Does this work now with version 4 beta?

Thanks.

STARTTLS is not supported, even in the beta. In theory it can be but I need to make few changes for it to work so it will have to wait for now I'm afraid. When I wrote the current version it was impossible to do with PHP, but now the required functions exist should I choose to do this

Please 'choose to do this'!
