Send email from 2 VPS via either 1 of the VPS

[lwt]

Hi, I have 2 VPS from different hosting provider both running WHM/cPanel.

1. VPS A is in US with IP x.x.x.100
2. VPS B is in Asia with IP x.x.x.200

May I know if it is possible to setup WHM/cPanel so that all the domains across both VPS only send email via through 1 VPS?
Eg,
- all domains on VPS A & VPS B emails are to be sent via VPS B.

Can advise what should be done is the above is possible?

Thanks.

Hey there! It might be easiest to setup VPS B as a smarthost of VPS A. We have some more details on doing this with third-party servers here:

How to Set Up a Smarthost SMTP Relay with cPanel | cPanel Blog

Learn how a Smarthost improves email deliverability and how to set up a Smarthost SMTP relay with cPanel and the Exim mail transfer agent.

so you could likely modify those instructions to work with a cPanel server as well.

Thanks cPRex.

Does that also mean that, without subscribing to 3rd party Smarthost or Reconfigure my VPS, my current VPS running (cPanel/WHM) purely hosting Web/Email can also be use as a SmartHost for another VPS also hosting WEB/Email in another geographic location by following the instructions in "How to Setup a SmartHost SMTP relay with cPanel"

Yes - those instructions *may* not be enough to get a cPanel -> cPanel configuration working properly, but I know it has been done by other users. If you run into trouble, make another post and we'll see if we can help.

Hi cPRex, Thanks for your reply. Appreciated .

Appreciate if you able to provide me a link to some typical or standard "guide/documentation" on how to configure cPanel to allow an existing VPS "B" (cPanel/WHM) that is currently hosting WEB/EMail to be able to become a Smarthost SMTP Relay for another cPanel/WHM VPS "A" to use?

Thanks in Advance.

Unfortunately I don't have such a thing ready to go. If you get it working you could post a guide with the steps you used to help out other users in the future.

Thanks cPRex. OK, Noted. Will try to figure out how to do it.

By the way, coming back to my initial plan of having to have 2 VPSes located in 2 different geographic location to send via 1 of the VPSes, beside using SMARTHOST SMTP Relay which you suggested, what are the other options?

Can you advise?
Thanks.

I don't know of another way off the top of my head. Now that I've thought about this for a bit, it may actually be easier to have both of the machines send through one third-party smarthost, as that would ensure mail doesn't get marked as spam or flagged for any other reasons, although that would incur an additional cost.

Either way, there's a way to get it working with any configuration you choose, it's just not something that is directly supported on our end.
