Dear list,
We've encountered an issue with Postorius after migrating from Mailman 2.1. It appears that Postorius is treating email addresses with differing capitalization as distinct user accounts. For example, <markus.grandpre@uni-konstanz.de> and <Markus.Grandpre@uni-konstanz.de> are being recognized as separate identities.
This is causing significant confusion. Users registered with one capitalization pattern are not seeing the list subscriptions and settings that were previously associated with their account (imported from Mailman v2.1) which used a different capitalization.
Is there a known configuration option or method within Postorius (or Mailman 3 itself) to normalize or unify account identification, effectively treating email addresses as case-insensitive for account matching?
We need a solution that ensures users see their correct list memberships regardless of the capitalization they use when logging in or that was used during the original Mailman 2.1 import.
Thank you in advance Markus
