When I use SquirrelMail with bincIMAP, I am limited to 27 mail folders, regardless of whether I am going against a Maildir++ depot or an IMAPdir depot. After that, bincIMAP complains with the following message:
133 NO STATUS failed: Maildir::scan::opendir("Trash/new/") == 0 (Too many open files)
where Trash is the last in the list. The full tcpdump trace can be found at http://www.instantiated.ca/download/squirrelmail-bincimap-too_many_open_files.txt.
The corresponding lines the the log file are:
Depot::getStatus("Trash") finding status
Depot::getStatus("Trash") failed!
Unable to aquire mailbox scan lock Trash/bincimap-scan-lock, Too many open files
Failed to release mailbox scan lock Trash/bincimap-scan-lock, No such file or directory
This is preceeded by a number of other error messages which are presented in http://www.instantiated.ca/download/squirrelmail-bincimap-too_many_open_files.log.
This error does not occur when SquirrelMail accesses a Courier-IMAP server, nor does it occur when Opera accesses the bincIMAP server. So, I believe that it is an error in the interaction between SquirrelMail and bincIMAP. I have been trying to trace it down in the code, but have been unsuccessful.
Regards, Henry
ps. I now have set up a controlled environment in my lab where I can test Opera, Netscape/Mozilla, Outlook and SquirrelMail against bincIMAP using a Maildir++ depot, bincIMAP using an IMAPdir depot and Courier (using Maildir++). HB
