Bug #29391 for Email-LocalDelivery: Alternative mbox locking methods

Hi, Email::LocalDelivery::Mbox uses flock() to lock the mailbox during delivery. However, Debian has a policy that requires all mbox handling applications to use fcntl() locks and "dot locking" for NFS safety [1]. To this end, the Debian package of Email::LocalDelivery [2] currently uses the attached patch to replace the locking method. It would be nice if Email::LocalDelivery::Mbox supported other locking methods natively. One approach would be to move the locking outside Email::LocalDelivery, so that different implementations could be packaged as separate modules. Alternatively, would you consider including the Debian patch as a compile-time enabled option or somesuch? I could try to rework it into one if you like. Please note that the patch is quite non-portable: getlock_fcntl() uses pack() in a Linux-specific way and the external 'dotlockfile' command is Debian-specific. See the thread starting at [3] for more information. My apologies for not bringing this into your attention sooner; Debian has been using this since January 2006 (version 0.09). Many thanks for your work on the Email::* modules!
