Swiftmailer + Symfony3.4: “Connection could not be established with host xx.xx.xx.xx”

I'm trying to connect to smtp server which is located in my local machine. Ping ok, telnet works fine, but from Symfony app i get "Connection could not be established with host .. "

Docker with ubuntu 18. PHP7.3

Below you have my actual configuration, but What i also tried was mixing smtp with ssl/465, tls/587, changing smtp to mail and try with all 3 enc/port configurations, and same thing with sendmail.

None of these worked. I used SwiftMailerLogger, nothing usefull came up, just that connection could not be established. In some configurations i got 'Connection refused' after main message.

My app is placed on docker machine, smtp daemon is in different location on same machine, but i also tried to do all configurations outside docker, still no luck.

Did anyone try to use swiftmailer with local smtp daemon?

My configuration:

mailer_transport: smtp
mailer_host: local_ip
mailer_user: user
mailer_password: pass
mailer_encryption: ssl
mailer_port: 25

I would assume this to be a docker issue, and better asked on serverfault – Jakumi
@Jakumi i tried to connect from outside docker as well as i described in my question, still no luck, but thanks ;) – msobczyk
I'm voting to close this question as off-topic because other users won't be able to have enough information and context to debug a networking issue. – yivi

Succeed!

First of all, auth-mode : plain, and :

stream-options:
    ssl:
        allow_self_signed: true
        verify_peer: false

Still using tls and 587 port.
