Up until fairly recently, the roaming user code in courier-imap was hardcoded off. This was because of a security bug in the vchkpw code that was being distributed with courier-imap.
Earlier this year I fixed the vchkpw code in courier to remove the security bugs. Also at the same time I arranged for modifications to be made to the courier-imap ./configure scripts so that roaming user support in courier-imap would be automatically enabled based on whether this functionality had been enabled in vpopmail
However, now that courier-imap is working properly, it exposed a bug in the roaming user code in vpopmail
The bug was present when the following combination of features were enabled : * courier-imap with authdaemon * vpopmail with roaming users and not with SQL auth backend
The bug resulted in temp files being created, and then never removed. Given enough time/logins, the directory/disk would completely fill with these temp files resulting in system failure.
It is safe to delete any old examples of these tmp files from your hard disk (ie older than about 1 hour)
I am not sure when the next builds of vpopmail are to be released, but it is possible for you to grab the patched builds direct from the CVS system with a command like this :
to get the latest 5.4 build (5.4.4 pre-release)
cvs -d:pserver:[EMAIL PROTECTED]:/cvsroot/vpopmail login (press enter when prompted for a password) cvs -z3 -d:pserver:[EMAIL PROTECTED]:/cvsroot/vpopmail checkout -r stable-5_4 vpopmail
or to get the lastest 5.5 build (5.5.1 pre-release)
cvs -d:pserver:[EMAIL PROTECTED]:/cvsroot/vpopmail login (press enter when prompted for a password) cvs -z3 -d:pserver:[EMAIL PROTECTED]:/cvsroot/vpopmail checkout vpopmail
One other thing to note about courier-imap and vpopmail roaming users... If you enable authdaemon in courier, then imap-before-smtp will not work, as when courier is running in authdaemon mode, the IP address of the client is not available to the vchkpw code in courier. If you want to be able do imap-before-smtp, you have to compile courier --with-authvchkpw --without-authdaemon
