I've also tried that but without success. I think the strace confirms
that the condition check isn't run with the previously looked-up access
rights (uid=2001 gid=100). If this is the expected/correct behavior can
only be answered by Jeremy:

   write(2, " 3255 getpwnam() succeeded uid=2001 gid=100\n", 44) = 44
   getpid()                                = 3255
   write(2, " 3255 checking \"condition\" \"${if exists{$home/.imapmail
   /cur}}\"...\n", 66) = 66
   stat("/home/tom/.imapmail/cur", 0x7fff58dba500) = -1 EACCES
   (Permission denied)
   getpid()                                = 3255
   write(2, " 3255 localuser_maildir router skipped: condition
   failure\n", 58) = 58


Cheers,
Juergen
