TCP traffic port

[kamnev999]

Good afternoon.
Tell me where and how can I change the outgoing TCP traffic port (port 25) to port 588?

I'm going to presume it is somewhere in here but not really sure to be honest

postal/app/lib/smtp_client/endpoint.rb

Line 54 in fd3c7cc

def start_smtp_session(source_ip_address: nil, allow_ssl: true)

I can't find this path

[willpower232]

It will be inside the docker container

[kamnev999]

def start_smtp_session(source_ip_address: nil, allow_ssl: true)
# @smtp_client = Net::SMTP.new(@ip_address, @server.port)
@smtp_client = Net::SMTP.new(@ip_address, 588)

  @smtp_client.open_timeout = Postal::Config.smtp_client.open_timeout
  @smtp_client.read_timeout = Postal::Config.smtp_client.read_timeout
  @smtp_client.tls_hostname = @server.hostname

after that, I restarted POSTAL.

It's still trying to send via port 25
Are there any other solutions?

If the code change is definitely still there after you restarted Postal then I'm not sure what the solution is.

I don't know if you can forward a port internally using iptables for outgoing traffic. I know you can do it for incoming.

When redirecting via iptables, it still tries to send via port 25
