Hello,
I'm trying to track down where MailWizz may still be caching or referencing an old sending IP address that is no longer configured anywhere in my current setup.
The issue specifically happens during list imports.
When importing a new list, MailWizz appears to still perform Cloudmark-related checks against an old IP address that is no longer active or assigned to any current delivery server.
Example message/log reference:
"Cloudmark Sender Intelligence lookup/check for IP 159.183.67.23"
That IP is no longer being used anywhere in my active configuration. Also, when I check cloudmark, it's noit listed anymore.

Background:
My questions are:
Any guidance would be appreciated.

That IP is no longer being used anywhere in my active configuration. Also, when I check cloudmark, it's noit listed anymore.

Background:
- The IP was previously used in an older sending configuration.
- It has since been completely removed from active use.
- The IP is no longer attached to any delivery server, bounce server, or sending domain.
- Despite this, Cloudmark-related checks during imports still seem tied to that old IP.
- Delivery servers
- Bounce servers
- Sending domains
- Tracking domains
- Cron jobs
- General MailWizz settings
My questions are:
- Does MailWizz cache Cloudmark or blacklist-related IP data internally?
- During list imports, where does MailWizz determine which IP to use for Cloudmark/reputation checks?
- Are there specific database tables, cache directories, queue tables, or import-related logs that could continue referencing a removed IP?
- Is there a recommended cleanup process for fully removing legacy IP references from MailWizz?
Any guidance would be appreciated.
