Hello peeps!
I have a Symfony Flex (v4) app on one of my droplets. I am using SwiftMailer in my app so i can send emails. It sends to another host (a mail server) the email so it can handles it.
The MAILER_URL is in an Apache2 SetEnv variable and it something like this:
SetEnv MAILER_URL "smtp://amazing.domain.org:25?etcetcetc"
The log of my applications says that it timed out
[2018-03-17 21:24:36] app.ERROR: Exception occurred while flushing email queue: Connection could not be established with host amazing.domain.org [Connection timed out #110] [] []
I am starting to believe that something is blocking it… maybe i need to add some outbound rule… any ideas?
Any rule i have to add to my firewall? to my ufw Ubuntu droplet?
Thanks for the help in advance. I love this community. Much love.
