I think you're confused.
You already have mail.labbrands.com set up as the MX record for labbrands.com. And it has an A record with the same address as your webserver.
I'm working with the hostgator mailserver, we are not running a local mailserver.
As suggested I added an A record like this: [image: image.png]
Is it correct? is it redirecting to my Ip so I can redirect it to my postfix/mm3 server?
So if you're getting e-mail on that domain, there's another e-mail server running on that IP address. You can't have 2 servers on port 25. In that case, as has been noted before, you'll need to setup a relay in that server, not a firewall redirect. Depending on your MTA, you would need to relay to your internal server. And make sure your firewall setup allows your MTA to do this.
We can see it's EXIM:
telnet mail.labbrands.com 25 Trying 192.185.51.89... Connected to mail.labbrands.com (192.185.51.89). Escape character is '^]'. help 220-gator4137.hostgator.com ESMTP Exim 4.87 #1 Thu, 03 Aug 2017 15:47:48 -0500 220-We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail. 214-Commands supported: 214 AUTH STARTTLS HELO EHLO MAIL RCPT DATA NOOP QUIT RSET HELP quit 221 gator4137.hostgator.com closing connection Connection closed by foreign host.
Or, consolidate all your e-mail to one server - which is a lot easier to manage unless you have a really big operation. Postfix is probably the right choice, but requires more setup.
Although Mailman3 configuration is not well documented (as you've discovered), you may want to get help from someone with more general network and mail experience. You're now into territory that is, as Simon indicated, not Mailman-specific.

. I mean for incoming mail redirected from my hostgator hosting, because when I suscribe an email address MM3 sends a confirmation email, so I have to reply to be suscribed to the list.
As I said, for mail delivery you need to forward port 25 to the Mailman server.
Ok so I'll redirect in my zentyal firewall the port 25 to my local centos7 with postfix and MM3 with IP 192.168.1.42. Thanks Mark.
