I happened to be looking at /var/log/maillog, and see a number of these:
Jul 6 13:25:32 iredmail roundcube: <avoe4onr> PHP Error: ldap_list failed for dn=domainName=HIDDEN,o=domains,dc=HIDDEN,dc=com: Bad search filter (POST /mail/?_task=mail&_action=autocomplete?_task=&_action=)
I've only been running iredmail for a month or so, but I can look back into June around the start and see the same messages?
