[PATCH] Reset atime when leaving mbox/mmdf with new mail



Hi,

the attached patch is supposed to set atime=mtime-1 for mbox and mmdf
folders if they contain new mail upon sync as we do for other folder
types. This only works if $check_mbox_size is unset.

See also ticket #1362.

I think the patch is okay. But I don't know why the old code does
restore atime+mtime for the folder (and so I removed the update).

Anyone?

Rocco
