[PERDITION-USERS] Fatal error during/after TLS negotiation

Hello list, My perdition director seems to be working fine with unencrypted POP and IMAP connections, but logs the following when I try to connect from Thunderbird using TLS: Connect: 128.146.221.167->206.71.169.193 SELF: "* OK IMAP4 Ready yankee 0001de1f\r\n" CLIENT: "1 capability\r\n" SELF: "* CAPABILITY IMAP4 IMAP4REV1\r\n" SELF: "1 OK CAPABILITY\r\n" CLIENT: "2 STARTTLS\r\n" SELF: "2 OK Begin TLS negotiation now\r\n" username_mangle: username_strip main: username_mangle STATE_GET_SERVER Fatal error manipulating username for client "128.146.221.167": Exiting child What should I do to get TLS working?
