Ok thank you Abhilash, I'll check the MX records.

Hello,

I created a test list called: testlist1@labbrands.com

How do I do in order to redirect the incoming emails to that direction to my server with MM3 ??

You typically need to change the DNS records for you domain to redirect emails to your server. Particularly, MX Records are which relate to Emails.

I am not sure about how to do that with cPanel, but I think their docs/support might help with DNS settings.

Thanks

You have to configure the MTA that is the MX for the domain to relay the mail to the Mailman server.

I still don't get it. What if I just suscribe the members and then send the email to the suscribers the thing is that the email has to be received by mailman in order to resend it to the list suscribers right?

If all you want to do is send mail that you generate, you can use

mailman inject

to deliver the mail to Mailman on the local machine. The drawback of not being able to receive mail from the outside is Mailman won't receive bounce DSNs from remote servers.

You have to configure the MTA that is the MX for the domain to relay the mail to the Mailman server.

Our domain is: LABBRANDS.COM We have that domain config in a Hosgator hosting. The emails sent to labbrands.com go to our hosting, so how do I tell cpanel in hostgator hosting that the mails sent to the list ( mailing@labbrands.com) are redirect to the MTA (postfix) in my private server (we have static public IP address) ??

You can't redirect one email address using DNS! If you don't want to host an entire domain on your own server, I suggest using a subdomain (lists.example.con) instead. You could probably also redirect one email in cpanel to the subdomain, but I'm not sure how mailman and clients like emails with different domains... In theory postfix can send emails using any domain. You just have to make sure spf, dkim and PTR records are properly set. Otherwise you'll most likely get issues with rejected mail...

Create a DNS A record for lists.labbrands.com with the IP of the Mailman server. You will also want a rDNS PTR record pointing from the IP to lists.labbrands.com.

You can't do this. Hostgator or whoever manages the network (Telmex Colombia S.A. ?) has to do this.

I've created the DNS A record for lists.labbrands.com with the IP but I don't know the port that it uses so I can make a port redirect to my local ip address wich is 192.168.1.42, do you know the port?????

You need to forward port 25 for SMTP mail delivery and if you want the web UI (Postorius and HyperKitty) accessible from the outside, port 80 for http and/or port 443 for https https://www.iana.org/assignments/service-names-port-numbers/service-names-po....

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.

-- Mark Sapiro mark@msapiro.net The highway is for gamblers, San Francisco Bay Area, California better use your sense - B. Dylan

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.

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.

You've said you're working with labbrands.com.

labbrands.com has address 192.185.51.89 mail.labbrands.com has address 192.185.51.89 www.labbrands.com is an alias for labbrands.com.

telnet proves that Exim is running on that IP address. Either you're running it, or hostgator is redirecting the SMTP ports.

You added: lists.labbrands.com has address 190.145.27.66

Presumably that's a different machine.

So that now needs an MX record, and a firewall routing. And the SPF records ... and spam and virus filters, and all the other stuff you need to setup an independent, public-facing smtp server.

But at least you won't have to relay.

Good luck.

Hello!

Just to let you know, the problem with the email reception was that I was thinking that the email was coming from my hostgator panel, but I was wrong, it's coming from Google (as I use gmail) so that was the problem, I have to open the port 25 to any computer not just my hostgator server..

Have a great day. Bye.

You've said you're working with labbrands.com.

labbrands.com has address 192.185.51.89 mail.labbrands.com has address 192.185.51.89 www.labbrands.com is an alias for labbrands.com.

telnet proves that Exim is running on that IP address. Either you're running it, or hostgator is redirecting the SMTP ports.

You added: lists.labbrands.com has address 190.145.27.66

Presumably that's a different machine.

So that now needs an MX record, and a firewall routing.

I added the MX record on our hostgator hosting like this: [image: image.png]

Is it correct???

Your screen shot, along with the excessive quoting, only caused your post to be "too big".

All the screen shot says is you have two MX records. The higher priority, 0, is mail.labbrands.com and the lower priority , 1, is lists.labbrands.com.

What this means is mail to the domain will be delivered to mail.labbrands.com unless that server is somehow unreachable in which case lists.labbrands.com will be tried.

This is probably not what you want.

I hate to say this at this point, but you are on a cPanel host. cPanel provides a functional Mailman 2.1 service. You might save yourself a lot of grief by just using that.

Should I configure my private Centos7 server with subdomain lists.labbrands.com?

That's what I suggested

Ok, Thanks Simon I will do it as suggested by you

...

Doing so how do I redirect the email to the private Centos where postfix and MM3 are installed? This really doesn't have anything to do with mailman. There are tons of tutorials out there. Generally you should try to find answers yourself and only ask when you couldn't find anything. People are motivated to answer if they find questions interesting and think they might learn something themselves. If they think the question can be easily answered using a Google search, they are generally less inclined to respond...

You guys have implemented MM3 before me and I think your experience is more valuable than a google search and believe me I've search on google about this, so If you know a site/forum where is explained please send the link. Thanks againa Simon
