Mailertable equi

[switala]

How do I setup relays for a domain in CPanel. Just like I always do in the /etc/mail/mailertable in Sendmail.

I have a domain's email that I have to relay to a private IPAddress on the internal network

domain.com smtp:[192.168.0.9]

Thank you

Did you find a solution?

Not tried it, but I guess you could use a smart router in exim:

Just cracked it - spent the afternoon trawling around google, and finally pieced together this solution - a quick how-to:

1. Type the following when logged in via SSH

touch /etc/staticroutes
pico /etc/staticroutes

2. Add entries in the format:

domainname.com: target.mail.server

3. Press CTRL-O to save the file, then CTRL-X to exit the pico editor.

4. In WHM, under 'Service Configuration' choose 'Exim Configuration Editor', then click 'Switch to Advanced Editor'.

5. Scroll down to the 'ROUTERS CONFIGURATION' section, and in the white space underneath, add the following:

static_route:
  driver = manualroute
  transport = remote_smtp
  route_data = ${lookup{$domain}lsearch{/etc/staticroutes}}

6. Scroll to the bottom of the page and click 'Save' - Exim will automatically restart.

Well chuffed, since I can now route mail for some of my customers domains, once they've been scanned for viruses and spam on my cpanel servers (I use the RVSKin virus/spam solution/howto), to their Exchange servers...

Excellent! Well done thank you for posting the implementation too.

 

[forlinuxsupport]

Wow.. works like a charm.

Thanks very much for the BRILLIANT post...

What happens if the remote mail server is down? Does the mail accumulate on the source server until the remote server becomes available?

I'm not 100% sure, but it most likely would queue it for later delivery.

etc etc

I also posted a post on this, and I was told to search for smart routers. It seems to work just fine, until I specify the port number; then I get:
2005-12-14 22:25:16 1Eme7f-0004EB-TZ == xxx@xxx R=static_route T=remote_smtp defer (22): Invalid argument
Anyways, I have to forward mail to another port too; any possibilities on that ?

Thanks

I'm sure I got this from chirpy but this is what I'm doing and it works perfect.


ROUTERS

smart_route:
  driver = manualroute
  route_data = ${lookup{$domain}lsearch{/etc/staticroutes}}
  transport = remote_smtp_smart

TRANSPORTS

remote_smtp_smart:
  driver = smtp
  port = 6625
  hosts = ${lookup{$domain}lsearch{/etc/staticroutes}}
  hosts_override

 

[Acieke]

Okay, thanks for that, I added the second code block, changing 6625 to the port of the destination mail server..
But now I get the following error for all queued and new sent messages:
2005-12-15 14:30:44 1Em8pc-0001lO-6H == xxx@xxx R=static_route T=remote_smtp defer (-53): retry time not reached for any host


Any ideas?
Thanks
Frederic

The error would suggest that exim is not able to connect from your server to the remote IP on that port. Have you tried logging into the cPanel server and using:

telnet ip-of-server 6625

Make sure that you get the SMTP banner. type quit to end the session.

If that works, then perhaps you don't have the correct details in your /etc/staticroutes file?

Sorry to open an old post.

Will the steps below get cpanel server to accept mail and scan it for spam and then relay it on ?

ROUTERS
Code:

smart_route: 
             driver = manualroute
             route_data = ${lookup{$domain}lsearch{/etc/staticroutes}} 
             transport = remote_smtp_smart

TRANSPORTS
Code:

remote_smtp_smart: 
                driver = smtp 
                port = 6625 
                hosts = ${lookup{$domain}lsearch{/etc/staticroutes}} 
                hosts_override

Ive got this in routes and it DOESNT scan the email it just relays it on fine.

ROUTERS

static_route:
  driver = manualroute
  transport = remote_smtp
  route_data = ${lookup{$domain}lsearch{/etc/staticroutes}}

 

[forlinuxsupport]

nope looks like using static_route and smart_route do NOT scan email for spam...

anyoen know how to ge tthat to work ?

 

[forlinuxsupport]

I got this direct from cpanel to make the relaying server also scan the emails.

This can be done simply by adding the aforementioned condition to the static_route router, which is presently defined in your exim configuration:

static_route:
driver = manualroute
condition = "${perl{checkspam}}"
transport = remote_smtp
route_data = ${lookup{$domain}lsearch{/etc/staticroutes}}

How do I specify all domains? (talking about point number 2)

Thanks.

Hi

Just like this.


forlinux.co.uk: 200.0.0.56
forlinuxhosting.co.uk: 200.0.0.57

Just list all of them on right and ip on left bit of command line scripting


Left = domain hosted on the server that you want to do the forwarding on.

IP / Domain on right = address of server you want to relay to (e.g. exchnage server)

Regards
Andy

Just an addendum to this thread.

You MAY need to alter your exim_outgoing.conf with the same router info. Maybe thats a given but everyone seems to only mention exim.conf and it took me days to realize it needed to go into the outgoing.conf

 

[chirpy]

So long as you correctly put add the router information to the exim configuration editor, then /scripts/mailscannerupdate will automatically copy the static router code into both exim.conf and exim_outgoing.conf - you should never need to edit exim_outgoing.conf (or exim.conf for that matter).

 

[WestBend]

I hadn't updated my prior post yet. I was using a set of instructions from the web which had me directly altering the exim.conf however i did not know that editing it via WHM actually updated multiple conf files i.e. exim.conf and exim_outgoing.conf. When i followed the instructions exactly and went through WHM it was very simply .
