[PERDITION-USERS] upgrading from perdition-1.15 to perdition-1.18

Hi All, I've been trying to upgrade from perdition 1.15 to perdition 1.18 without any luck. The behaviour is different with regards to MySQL data which are returned. The query: select mail_username,mail_host_map,143 from access_maps where mail_username='cami(a)24.com'com'; +---------------+-------------------------------------------------+-----+ | mail_username | mail_host_map | 143 | +---------------+-------------------------------------------------+-----+ | cami(a)24.com | f2ef77fe86754109b347dd97a79444eb(a)152.111.194.93 | 143 | +---------------+-------------------------------------------------+-----+ In 1.15 "f2ef77fe86754109b347dd97a79444eb" is correctly returned as seen here: Aug 13 16:18:25 mailstore01 imapd: LOGIN: DEBUG: ip=[::ffff:127.0.0.1], command=LOGIN Aug 13 16:18:25 mailstore01 imapd: LOGIN: DEBUG: ip=[::ffff:127.0.0.1], username=f2ef77fe86754109b347dd97a79444eb Aug 13 16:18:25 mailstore01 imapd: LOGIN: DEBUG: ip=[::ffff:127.0.0.1], password=XXXX Aug 13 16:18:25 mailstore01 imapd: authdaemon: starting client module Aug 13 16:18:25 mailstore01 imapd: authdaemon: ACCEPT, username f2ef77fe86754109b347dd97a79444eb Aug 13 16:18:25 mailstore01 imapd: LOGIN, user=f2ef77fe86754109b347dd97a79444eb, ip=[::ffff:127.0.0.1], protocol=IMAP (the imap server being used is Courier) In 1.18 "cami(a)24.com" is being returned and passed onto Courier instead of "f2ef77fe86754109b347dd97a79444eb" Aug 13 15:07:15 mailstore01 imapd: LOGIN: DEBUG: ip=[::ffff:152.111.194.109], command=LOGIN Aug 13 15:07:15 mailstore01 imapd: LOGIN: DEBUG: ip=[::ffff:152.111.194.109], username=cami(a)24.com Aug 13 15:07:15 mailstore01 imapd: LOGIN: DEBUG: ip=[::ffff:152.111.194.109], password=XXXX Aug 13 15:07:15 mailstore01 imapd: authdaemon: starting client module Aug 13 15:07:15 mailstore01 imapd: authdaemon: REJECT Can anyone tell me how to revert back to the old behaviour to how to go about trouble shooting this?
