Mailer timeout

[seddighi78]

Symfony version(s) affected: 4.4.2

Description
I'm using Mailer component for send email in Symfony and set env variables for MAILER_DSN

 MAILER_USERNAME=mailer@example.con
 MAILER_PASSWORD=**************
 MAILER_DSN=smtp://$MAILER_USERNAME:$MAILER_PASSWORD@mail.example.com:465

the emails was send but throw error for timeout:

request.CRITICAL: Uncaught PHP Exception Symfony\Component\Mailer\Exception\TransportException: "Connection to "ssl://mail.example.com:465" timed out." at path/path/vendor/symfony/mailer/Transport/Smtp/Stream/AbstractStream.php line 81 {"exception":"[object] (Symfony\Component\Mailer\Exception\TransportException(code: 0): Connection to \"ssl://mail.grandsocial.net:465\" timed out. at path/path/vendor/symfony/mailer/Transport/Smtp/Stream/AbstractStream.php:81)"} []

i think this is bug or if not please help to solve this.
thanks

This is not bug. The timeout is default 5 second defined in:
SocketStream::$timeout = 5;

There is no configuration here to set this time nor any setter. Increase value anyway.

@seddighi78 can you confirm temporary solution ?

[seddighi78]

@michaljusiega I'm using a try-catch to control the throws of the mailer. the mail was successfully sent but time out happened.

[michaljusiega]

Yes because your SMTP server probably analyze your mail too slowly so you got a exception for this reason.

[seddighi78]

Do I have to wait for this problem or is there a right solution?

@seddighi78 this is not a bug, as @michaljusiega has mentioned, your server is taking too long to responed and symfony mailer is timing out.

if you want to increase the timeout, you can do so using :

$transport->getStream()->setTimeout($timeoutInSeconds);

@azjezz How can i change timeout from event listener or controller? I can't change timeout from configuration

[fabpot]

I would highly recommend to fix the latency of the server if possible. If not, configure default_socket_timeout in the php.ini file (which will be available for SMTP server as of Symfony 5.1). In the meantime, using the snippet given by @azjezz will work as well.

Thank you @fabpot

The only way of solving this in 4.4 is creating a custom factory that configures the timeout of the socket ?

[apphancer]

Here's my problem with this: Application is running on Symfony 5.0 and files between 3-4 MB need to get attached. In the development environment, we are using Mailhog on a Docker container - the former being notoriously slow at processing emails with attachments. In this scenario, we are getting a ["/app/vendor/symfony/mailer/Transport/Smtp/Stream/AbstractStream.php","Connection to "localhost:1025" timed out."] error from our Console command. Emails are still being sent and received successfully.
default_socket_timeout is set to 60 in the ini settings used by PHP CLI, but this seems to be ignored.

I solved it for v4.4 by setting timeout in the decorated EsmtpTransportFactory::create method.
I blogged about it.
