Sending All Mails [SMTP / PHP Function] Thruogh Another Server

[Beny]

Hello Everyone,
recently my webservers IP which is hosted in netelligent has been blocked by Yahoo! and Hotmail servers, tried changing ip but didnt work because whole ip range of this datacenter was blocked !
so i need to send all mails [ALL MAILS, NOT only SMPT] through another server which is located somewhere with trusted IPs like Singlehop or XLHost, so what do we need on both sides and what configuration should we apply ?!

no answer ?

You are wanting to use a smart host router to route all emails through the smart host rather than directly from your machine. Please note that, for exim, your IP is still going to appear in the sender header as one of the IPs that handled the routing regardless, although it won't be the final IP routing the message.

Here is a prior post where I discussed using a smart host router:

other side should be cpanel server, right ?! with considering that IP is not changed in the header of the sent mail would these mails bypass yahoo and hotmail blockers ?!

Yahoo and hotmail do not do deep scanning, so the final IP that sends the message would be what they should be considering for determining if an email will pass into an inbox on their services.

I don't get what "other side should be cpanel server, right ?!" means exactly. Are you asking if the smart host server that will be filtering the emails should also have cPanel on it? It doesn't have to have cPanel on it, it just needs to be capable of receiving and then sending out the emails. If the second machine were also cPanel, you'd have to make that machine a relay for the other machine.

So the smart host machine (if it has cPanel) would need to have the IP for the initial machine into a file you create called /etc/alwaysrelay and then restart exim on that smart host machine. This should be all that is needed to allow the smart host machine to relay the emails from the initial machine.
