after an update 9.4.6 -> 9.5.5 I can't make receiver work right.
Any message from user not present in glpi can't be purged from mailbox.
Other messages act as they should.
I tried console tools (key change, task unlock) - no luck
Lower SSL ver - no luck
Allow anonymous tickets are ON - still no luck
IMAP with certificate is used and it was fine on previous version.
mailgate.log shows - "Malformed header detected" and that's all.
