Public bug reported: We have seen (very rarely) cases where a recipient address has a quoted local part such as "jr."@example.org. This results in a VERPed sender address like list-bounces+"jr."=example.org@example.com which is syntactically invalid. The VERPed sender should be "list- bounces+jr.=example.org"@example.com in this case. I.e., the entire VERPed sender local part should be quoted, not just the recipient local part. This also requires BounceRunner to recognize this and restore the original local part. ** Affects: mailman Importance: Medium Assignee: Mark Sapiro (msapiro) Status: In Progress -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1731604 Title: VERP fails if the recipient address local part is quoted.
