Bug ID: 8302
Summary: util: idn_to_ascii: conversion to ACE failed
Product: Spamassassin
Version: 4.0.1
Hardware: PC
OS: Windows 10
Status: NEW
Severity: normal
Priority: P2
Component: Plugins
Assignee: dev@spamassassin.apache.org
Reporter: ruud.vd.h...@gmail.com
Target Milestone: Undefined
I installed the Net::LibIDN2, version 1.02 optional module, since doing that i
see many entries in my logs stating 'util: idn_to_ascii: conversion to ACE
failed, domain label longer than [x] characters'
By looking for a common reason i noticed this seems to be caused by the fact it
is ran against the full URI, eg: including query strings, like:

failed, domain label longer than 63 characters:

The conversion of internationalized domain names should not process query
strings, should it?
