I was using 1.2.3 previously without any problems. I upgraded to 1.3.1 and compiled and install it the same. I using vpopmail with MySQL support. However now when a user log's in it shows:

imaplogin: LOGIN, user=te...@checkoutisle.net imaplogin: LOGOUT, user=te...@checkoutisle.net

in the log so they get logged in and can see what messages there is. And then they can click on a message. But after a period of time or if they try to delete the messages it will show the following in the log:

imaplogin: LOGIN FAILED

and return the users back to the webmail login screen. I am using IMP horde for my web mail. I have not touched it just did the upgrade to the Courier. I am using vpopmail-4.9.8. I saw there was some new configure line to work with vpopmail auth. Is this required now?
