Send messages by GMail's SMTP
« on: November 09, 2013, 09:57:45 pm »
Hello,

How can I send messages from local network to the internet by using GMail's SMTP?

P.S. I was using Citadel Groupware which offers very easy configuration to use external SMTP (relay SMTP).

Do you mean  using smart relay after Zentyal ?

I'm not sure if this works to me because I never used it before. I just want to use Zarafa as a replacement for desktop applications (ex. Thunderbird, Outlook) so the users can simply contact each other inside the local network and outside it (to the internet)

Because you already have a full blown SMTP / MAIL server then actually rather than the hassle of 3rd party email hosting yourself is probably easier if you have a number of users.

But for that you really need a static IP so you can have a rDNS pointer with your domain name.

So there are two ways.

A. Hosting provider in essence what gmail is.

Email boxes on hosting provider and forward using an SMPT relay.
You have the email accounts hosted as there is a domain to send them to and in Zentyal setup up external accounts to download to the specific email user.
Sending uses the SMPT smart relay in the Mail settings.

This is a usual setup up if you don't have a domain name.
Also if you don't have a static IP with rDNS pointers to your domain name you will find emails returned to you or spammed.

B.
You have an domain name, static IP and your ISP will provide rDNS
Then setup up a virtual mail domain.
In your domain registry have a A record @ with your IP address of your static IP
Sometimes you don't even have to supply an MX record but this is stored in the DNS settings with the above.

I don't know what the relay policy is with the gmail smpt.
