Transport Config & Mailtrap

Hi there:
When I set up my .env with my Mailtrap credentials, I got this error:
Warning: stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages:
error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed

Extra set up required? :)

I got this from Ubuntu:
SSL Version => OpenSSL/1.1.1c
openssl
OpenSSL support => enabled
OpenSSL Library Version => OpenSSL 1.1.1c 28 May 2019
OpenSSL Header Version => OpenSSL 1.1.1d 10 Sep 2019
Openssl default config => /usr/local/ssl/openssl.cnf
openssl.cafile => no value => no value
openssl.capath => no value => no value
Native OpenSSL support => enabled

Does anybody know if this setting is wrong? Any help would be welcome. :)

Best regards.

Obviously, this is a no-related Symfony issue nor Mailer but local setting (Ubuntu)

Yo Abelardo L.!

Hmm. Well, you were thinking about the same thing I was already - is the openssl php extension running. And yes, it appears it is ;). Because you're using Mailtrap... my guess is that your Mailtrap does not have a valid SSL certificate... which totally makes sense, as this is just a local server :). In fact, I think (?) that Mailtrap might not have a secure connection setup - https://github.com/sj26/mai.... Basically, I think (?) that Mailer should be communicating to Mailtrap in a non-secure manner. If I'm reading Mailer's code correctly, as long as you use port "25" to connect to Mailtrap, it *should* connect *without* "tls".

If you need to do some extra debugging, I would do some "dumping and die'ing" inside this class - https://github.com/symfony/... - to see if tls is ultimately set to false or not.

Let me know if that helps!

Cheers!

Hi there!
I have reinstalled my Ubuntu copy and all it worked!

What I told you: it was a misconfiguration from my [past] Ubuntu copy. :)

Hey AbelardoLG,

Ah, good job! Yeah, sounds like so... and we're happy you got it working finally! :)

Cheers!

Hi there!

I'm afraid it's not related to Mailtrap since I have tested it with a virtual machine and it worked (althought it was with my own email server data).
I think is due to a misconfiguration of my Ubuntu.

Anyway, thanks for your response. :)

Best regards and happy New Year!

Hi, I'm having a really strange error trying to configure this. The error is happening in my CI step when I try to set up the DB schema for the test database.

I'm using mailslurper instead of mailtrap by the way. In my .env file I have:
MAILER_DSN=smtp://mailslurper:2500

However, when I try to create the test DB, I get this error message:

$ php bin/console doctrine:schema:create -e test

 !
 ! [CAUTION] This operation should not be executed in a production environment!
 !

 Creating database schema...


In TransportFactory.php line 54:

  No transport supports the given Messenger DSN ""..

Do you have any idea what could be going on here? Why does it think the DSN is an empty string?

Hey Cheshire,

That's odd. Is it possible that you are overwriting that env var in a .env.test file (or .env.local.test)?
By the way, I fixed your comment format :)

Cheers!

Looking at the source code where the error comes from... https://github.com/symfony/symfony/blob/6.3/src/Symfony/Component/Messenger/Transport/TransportFactory.php#L54

It looks like it simply doesn't support smtp:// protocol in the DSN? How can that be right?

Hey Cheshire,

Sorry for my late reply. I just realized there is confusion. You got an error about the MESSENGER DSN but changed the MAILER DSN env var. Those env vars serve different purposes. Can you double-check that the MESSENGER_TRANSPORT_DSN env var is not empty? Besides that, do you have problems with any other env var? What happens if you use any other built-in transport?
If nothing works, try clearing the cache manually rm -r var/cache/* and upgrade those components

Sorry, this is the version I'm on- https://github.com/symfony/symfony/blob/5.4/src/Symfony/Component/Messenger/Transport/TransportFactory.php#L54

Yeah, looks like the DSN is blank for some reason. Something must be wrong with the environmental variables, I just wish I could figure out what! Any ideas aside from the .env.test? Why would it not be seeing what's in the .env file if it's not overridden anywhere?

Thanks for replying. No, there is no MAILER_DSN in my .env.test file. Even when I add MAILER_DSN=smtp://mailslurper:2500 to my .env.test file, I get the same error message.

Wow, it really messed up the formatting. In my .env I have MAILER_DSN=smtp://mailslurper:2500

Good morning, in my case, I have a problem, symfony does not autowrite the transport configuration in mailer.yml but uses the default configuration:

    "main" => Symfony\Component\Mailer\Transport\Smtp\EsmtpTransport {#679 ▼
      -authenticators: array:4 [▶]
      -username: "user"
      -password: "pass"
      -started: false
      -restartThreshold: 100
      -restartThresholdSleep: 0
      -restartCounter: null
      -pingThreshold: 100
      -lastMessageTime: 0
      -stream: Symfony\Component\Mailer\Transport\Smtp\Stream\SocketStream {#713 ▶}
      -domain: "[127.0.0.1]"
      -dispatcher: Symfony\Component\HttpKernel\Debug\TraceableEventDispatcher {#141 …8}
      -logger: Symfony\Bridge\Monolog\Logger {#692 …8}
      -rate: 0
      -lastSent: 0
    }

Hey Ali!

Hmm. What does your mailer.yaml look like? And what config do you have in that file that you don't see here? Also, can you tell me where exactly this dump is coming from?

Cheers!

hi, i'm using symfony6 and mailtrap. With the same configuration, the mail doesn't work. In the log says "Sending message Symfony\Component\Mailer\Messenger\SendEmailMessage with async sender using Symfony\Component\Messenger\Bridge\Doctrine\Transport\DoctrineTransport" but the smtp server is silent and mailtrap doesn't receive anything. There is something new that i must do? thanks

Hey Alessandro V.

Did you run php bin/console messenger:consume async

Cheers!

i used to send email without this command, please is there's any way that i can send mails without having to run php bin/console messenger:consume async in the background ?

Hey @Jose-M,

no problem, just tweak config/packages/messenger.yaml

framework:
    messenger:
        # ...
        routing:
            # ...
            'Symfony\Component\Mailer\Messenger\SendEmailMessage': sync

Cheers!

Thank you! works like a charm now. Now i want to know more about this messenger, it seems useful

Awesome!

BTW i have a tip for you https://symfonycasts.com/sc... ;)

Cheers!

Hi everybody, I am having en issue with Symfony 4 mailer. I have decided to migrate from Swiftmailer (which works just fine) but symfony mailer doesn't accept my DNS. The error comes up "mailer DSN is invalid". Digging into problem, I figured out than Symfony mailer doens't accept in password "#" simbol.

In file vendor\symfony\mailer\Transport\Dsn.php (line 42) this line is fail if (false === $parsedDsn = parse_url($dsn))
Example password "dfg4_d#dfg"
We can't not change email password, so we have to keep using Switfmailer. I think thant symfony team has fix it.
Best regards

Hi Viktoriia K.!

Excellent debugging to track down the issue! Here's aa PHP bug report describing your problem: https://bugs.php.net/bug.php?id=73754

Basically, your password is "supposed to be" URL encoded... and the new code is "enforcing" this. The fix should be easy though - URL encode the password. So, change # into %23.

Let me know if that helps!

Cheers!

Thank you very much. It works now.

HI. I've moved over to Mailer from SwiftMailer but can't find any option to use Office 365, is it possible to configure to use O365 or are hte options the ones listed in the main Symfony docs?

Cheers

Hey Steve,

Unfortunately I know very little about Office 365. Does Swiftmailer has an integration with it? Do you attach some docs directly from Office 365? Symfony Mailer allows you to attach files as attachments, so the whole doc will be sent to your addressee. And you can set that attachement via PHP resource, i.e. you don't need to get the content of the file with file_get_content() and add it to the email. Here's where we create a PDF file and attach it to the email: https://symfonycasts.com/sc... - I suppose you can do the same with your docs reading them from Office 365.

I hope this helps!

Cheers!

Thanks Victor however I may not have been 100% clear, it's about using O365 as a transport option rather than attachments. In SM I can use this:

MAILER_URL=smtp://smtp.office365.com:587?encryption=tls&username=user@domain.tld&password=password1234

Does that make sense?

Steve

Hey Steve,

Oh, now I see :) Yeah, unfortunately, Symfony Mailer has native integration only with the next several transports: https://symfony.com/doc/current/mailer.html#using-a-3rd-party-transport . But it does not mean you can't use it for other services like Office 365. As long as they work via SMTP - it just should work. You just need to set the correct value for MAILER_DSN env var, see https://symfony.com/doc/current/mailer.html#transport-setup. So, you need to change the format a bit, e.g. username/password should be before the host. Try this one:

MAILER_DSN=smtp://user:password1234@smtp.office365.com:587?encryption=tls

Does it work for you?

Cheers!

Hi Victor, thank you for help and sorry for delay, I hadn't seen the notification.

This doesn't work unfortunately, it is something I had tried.

Steve

In fact it does work but the password has issues with certain characters... $ and or ^ are not good.

Thank you for the help. Have a great day

Steve

Hey Steve,

Ah, yes... I remember something like this, and if I'm not wrong, we even talked about it in the video? Yes, that's limitation of environment variables itself. You can easily replace them with other chars, like "*" or brackets I suppose.

Anyway, I'm glad you figured it out yourself!

Cheers!

I do have a local STMP-server that I wish to send emails from. When I was using swiftmailer, I could use:
MAILER_URL=smtp://localhost
Now when I try MAILER_DSN=smtp://localhost, I get an error:
<blockquote>
Warning: stream_socket_enable_crypto(): Peer certificate CN=mail.example.com' did not match expected CN=localhost'
</blockquote>
I tried just about everything, and when using this smtp-server from another machine (and providing all required credentials) I <u>can</u> use Symfony Mailer. But from the same machine... no luck. Any ideas what I could do differently?

I figured out what I could do differently, setting 'mail.example.com' in my hosts file under 127.0.1.1 seems to work!

Hey Dirk

I'm glad to hear that you could fix your problem. Thanks for sharing your solution with others :)

Cheers!
