Sending mail out
« on: May 26, 2012, 07:34:53 pm »
Ok i have a domain that is registered at godaddy.com

Domain: jnkbcs.biz

I have configured the Zentyal Server as best i know how and i am getting the following error message:

   connect to alt4.gmail-smtp-in.l.google.com[173.194.67.27]:25: No route to host

Where do i need to start or what needs to be done first.

With such error message ("no route to host") I would start with network & gateways rather than mail  ???
What's about traceroute?

Well, this could be also because your provider blocks access via port 25 (I didn't pay enough attention to the error message previously)

Ok i went to:
http://www.canyouseeme.org/

and this is my result:

Success: I can see your service on 108.244.112.63 on port (25)
Your ISP is not blocking port 25


I then opened a telnet session and here are the results:

telnet> open mail.jnkbcs.biz 25
Trying 108.244.112.63...
Connected to jnkbcs.biz.
Escape character is '^]'.
220 jnkbcsserv001 ESMTP Postfix (Ubuntu

not sure what else i need to do.

problem is not to see YOU but to see alt4.gmail-smtp-in.l.google.com from your server.
While connected to your Zentyal server, can you telnet alt4.gmail-smtp-in.l.google.com on port 25?

 8) which means that, most likely, your provider is blocking direct outgoing flow on port 25 (this to prevent spammers activity)
This also means that you have, again, most likely, to use your provider's MTA as smart relay...  ;)

I have AT&T dsl. How do I do that? And if that's the case how do I switch ports going out?  I am new to this so I'm learning as I go.

Did some reading and I noticed where some people suggested using smtp  tls ports like 465 and 587. How do I configure zentyal to use those?

This basically doesn't work because it would require that:
- your ISP authorizes such port
- and ALL target MTA enable such port too.

Reason why you are blocked - assuming our analysis is correct - is that your provider blocks outgoing flow on port 25.
Trying to workaround using another port works only for servers using such port. Unfortunately, your provider blocks port 25 because this is the standard port for SMTP  ;)

Another aspect to be taken in account: port 587 is used from MUA connecting to MTA. Between MTAs, port 25 is used first and then TLS might be activated, for what I understand.

Is there any reason why you don't want to enable smart relay ???
