It seems that to force the dotlock locking strategy, one needs to use the --with-homespool option. But then, mutt -v says:
MAILPATH="mailbox" Here, mailbox doesn't correspond to anything. So, is it a problem? Note that my only spool mailbox is an IMAP mailbox. But I need a locking strategy for the postpone and archive mailboxes (under NFS). As fcntl is not reliable here, I think I'll disable it and use dotlocking only. -- Vincent Lefèvre <[EMAIL PROTECTED]> - Web: <http://www.vinc17.org/> - 100% validated (X)HTML - Acorn Risc PC, Yellow Pig 17, Championnat International des Jeux Mathématiques et Logiques, TETRHEX, etc. Work: CR INRIA - computer arithmetic / SPACES project at LORIA
