Remove/disable spam filtering?

[mta]

Hi,

I haven't taken a look into this yet and thought I would ask the forum quickly before doing so.

We currently use a third party email filtering service with Ensim on nearly all of our shared servers and it works quite well.

Is there an article somewhere on completely removing or globally disabling "spamblocker" or whatever spam filtering is currently included with DirectAdmin?

Thanks!

If your /etc/virtual/use_rbl_domains file is empty most of SpamBlocker's features won't be used; it's turned off by default. Note: if your /etc/virtual/use_rbl_domains file is a link to /etc/domains, then be sure to NOT delete it, but rather to remove the link and recreate it as an empty file with the same ownership and file attributes as /etc/virtual/domains.

However, even if it's on, it won't do much unless your third party filtering service IP#s are on one of the blocklists it uses.

If installed SpamAssassin can be shut down and set to not restart on system start (just how you do it depends on your OS Distribution), but you have to comment out certain parts of the exim.conf file. You can certainly change or comment out any of the exim.conf file, but if you do, then you're responsible if you break it .

Thanks for the reply.

I see now, looking at the exim.conf file, that the configuration is pretty straightforward.

If it weren't for our few servers that aren't using the 3rd party filtering service and the desire to maintain only one config file, I would remove the rbl lines altogether. I may make a separate branch in git, as there will be other customizations relevant to these servers.

By default the exim.conf file is very straightforward. When I wrote the version currently in DirectAdmin I added a lot of comments, to make it even more straightforward. The latest one, version 3-beta, found here, has even more comments, and is much more straightforward.

You really don't have to; there's no overhead to speak of for domains not listed in the /etc/virtual/use_rbl_domains file; only the file lookup, and on most servers the file will be kept in memory after it's first access.

Of course you can; both the original file included with exim, and the changes I've made, are open source:
