In Progress CPANEL-36888 - Exim Configuration False warnings when redirecting to default routers

[Deion Yu]

Hello everyone,

Recently I had added a custom redirect router to the PREVIRTUALUSER section which redirects to the "virtual_user" router which comes with the exim.conf file by default. However, the Exim Configuration Manager Advanced Editor interface keeps on generating the following warning message:

Warning! directive_matcher could not parse error: 2019-02-28 18:01:55 cwd=/usr/local/cpanel/whostmgr/docroot 4 args: /usr/sbin/exim -bV -C /etc/exim.conf.test.work.1f698453
2019-02-28 18:01:55 Exim configuration error:
  new_router "virtual_user" not found for "my_previrtualuser_router" router

Both the Exim service and my custom redirect router are running and redirecting as expected despite the warning message. This leads me to believe that the warning message is being falsely generated due to the cPanel Exim validation routine not taking both my custom redirect router and the "virtual_user" router into account at the same time.

Am I right in thinking that the problem lies with the validation routine? If I am mistaken, then what would be the best approach to take to resolve this? If at all possible, I would like to avoid adding a duplicate custom router that mimic the "virtual_user" router.

Looking forward to hearing back and thank you for any help you can provide on this matter.

Hi @Deion Yu


Can you provide the exact custom router you added? I'd like to see if I can replicate.

Hello @cPanelLauren

Here's the custom router that was added to the PREVIRTUALUSER section.

magicspam_virtual_user_spam:
    driver = redirect
    domains = !$primary_hostname
    condition = ${if def:header_X-MagicSpam-Spam:{1}{0}}
    require_files = "+/etc/valiases/$domain:+/etc/magicspam/control/quarantine_local:+${extract{5}{::}{${lookup passwd{${lookup{$domain}lsearch{/etc/userdomains}{$value}}}{$value}}}}/mail/$domain/$local_part"
    headers_remove="x-uidl"
    data = "$local_part+spam@$domain"
    redirect_router = virtual_user

Hi @Deion Yu


Have you checked out magic spams forums? MagicSpam PRO for WHM/cPanel Release 2.1-9.1 is now available - Wizard IT Products

It does seem they had issues with this problem/similar issues previously. For this custom router, I would suggest discussing it with them first.

Hello @cPanelLauren

I'm actually a developer for MagicSpam and based on my testing the problem does not seem to be with MagicSpam in this particular case. As previously mentioned, the custom redirect router is working as expected. Running the buildeximconf and restartsrv_exim scripts from the command line yields no error messages or warnings. The issue seems to persist solely on the cPanel Exim Configuration Manager Advanced Editor interface as even when adding a bare minimum custom router like the following to the PREVIRTUALUSER section:

custom_virtual_user_redirect:
    driver = redirect
    condition = yes
    data = "$local_part+spam@$domain"
    redirect_router = virtual_user

The interface still produces the warning message:

Warning! directive_matcher could not parse error: 2019-03-06 21:00:19 cwd=/usr/local/cpanel/whostmgr/docroot 4 args: /usr/sbin/exim -bV -C /etc/exim.conf.test.work.837fd569
2019-03-06 21:00:19 Exim configuration error:
  new_router "virtual_user" not found for "custom_virtual_user_redirect" router

Any help you can provide on this matter would be greatly appreciated. Thank you for your continued support.

Hello @Deion Yu,

I've reproduced the reported behavior and opened internal case CPANEL-26137 to report the issue. I'll monitor this case and update this thread with more information on it's status as it becomes available.

Thank you.

Is there any update on this? Facing the same issue

There's no update on the status of this case to report at this time, however I'll continue to monitor it and report back here as soon as new information is available.

In the meantime, you can safely ignore this warning message when this happens, as the custom change is saved despite the message.

Thank you.

Hello,

some years later, is there some update on CPANEL-26137 ?
Facing the same issue here when saving "Exim Configuration Manager" / "advanced editor".
In fact not need to save, the modal popups just by showing the page.

PS : The "virtual_user_mailscanner router is added via an include

I can send my exim.conf and spambox.conf in a DM if you want to look at it

Thanks for your help

@Markif - the original case was closed as it was determined there would need to be a substantial redesign to that area of the interface in order to get it resolved.

If you're still seeing this issue could you open a ticket so we could do some additional testing?

 

[Markif]

@cPRex
Thanks for inviting to open a ticket to look closer into this !
Ticket = #94323336

 

[cPRex]

Thanks so much - I'm following along with that ticket now and I'll be sure to post our findings here.

Our team has created a new case for this behavior based on additional testing. If you're signed in to our ticket system, you can follow along with that here:

Just wanted to say, we are seeing this warning on every server too

It is utterly pathetic that this problem has been going on for years - if the developers are too dumb to fix this, FIRE THEM AND GET REPLACEMENTS! The company should have enough money to hire the best available, looking at the ridiculous monthly charges you collect.

And yes, the error is still around and did not magically disappear.

 

[Secmas]

I confirm that the issue is still alive.

 

[JoseDieguez]

yep, when using the editor, it pops up every few seconds..

 

[cPRex]

Thanks for letting me know this is still happening. At this point, it's unlikely this is getting fixed. My best recommendation, and I really wish I had a better plan B for all of you, would be for @JoseDieguez to reach out to their account manager and let them know that CPANEL-36888 is still ongoing and that you'd really like a fix. I'm sorry I don't ahve better news on this one.

 

[EneTar]

Same issue here, is there any workaround until cpanel fixes it?

 

[cPRex]

I'm not aware of any workarounds at this time either.
