Re: [Sqlrelay-discussion] Problem with Courier-IMAP using LD_PRELOAD

[David M. <dav...@fi...>]

Does Courier-IMAP call it many times to switch between different db's or
just once?  If not, then setting up the SQL Relay instance to point to
the db it needs to use and making mysql_select_db return true is
probably the best solution.  If so, then there probably isn't a good
solution at present.
