My Exim Configuration Changes Don't "Stick"

The only change I'm making is through WHM in
Service_Configuration-->Exim_Configuration_Editor

I change the Subject line prefix for spam from ***SPAM*** to [SPAM] (just because I have several employees with that filter on their email client)

Setting changes; I look at the exim.conf via SSH and the setting has changed.

The next morning, the setting is back to ***SPAM***

Is this a feature or a bug? If I change the RBL preferences will they reset as well? I'm guessing this is on the updates nightly??

This is from the /scripts/upcp log emailed to me:

>>

Can anyone shed any light on the correct procedure for making config changes permanent?

 

Well, that would solve the problem for now, until I go back and want to change something via WHM and then can't remember I've set the bit on the file to not updateable. I'll then pull the rest of my hair out and eventually remember then slap myself in the head.

Meanwhile, it's supposed to work, isn't it? And since there was no update last night (see log file entry) why the change back to default in exim.conf ????

 

Tried but no luck with chattr. Exim configuration keeps reverting.

Regarding your suggestion to use the Exim Configuration Editor in WHM. That's what I'm talking about! That's what I'm using!

I've tried the chattr command on the /etc/exim.conf file.

No, the settings keep reverting.

Here, for clarity, is the problem again:

I want to change just a few settings for Exim, via the WHM.

I login to WHM. I navigate to the 'Exim Configuration Editor.'

I check a few checkboxes to change some settings. I Save the configuration.

I check later in the day. My changes are still OK. They're there.

Spam has slowed to a trickle because of the new changes.

Next day I login to WHM and go to the Exim Configuration Editor.
The changes I made are not there. The checkboxes I checked are now "unchecked." The configuration is exactly like it was BEFORE I made the changes.

Of course, an update has run the night before.

My previous WHM server did not have this problem. Changes in Exim "stuck." Is it this version of WHM that's the problem? Is it a setting I'm overlooking?

I guess I can write a script to replace the Exim config file each morning with the one I've saved and restart Exim. But that would be kind of a kludge, wouldn't it? When WHM is supposed to work?

Help?!
