On my system mail is downloaded using fetchmail, which hands the mails to procmail; procmail then saves the mails in the correct mbox (for example each mailing list has its own mbox). Using mutt, the 'c' key is used to changed mbox and it defaults to the first mbox that has new mail. With kernel 2.6.16 'c' has no effects (mutt seems to think that there's no new mail). I think that the problem is related to the changes in: fs/xfs/linux-2.6/xfs_iops.c I've done a simple test with working and non working system: * With kernel 2.6.16-rc2 Empty file: kronos:~/Mail/Lists$ stat ML-testml-February-2006 File: `ML-testml-February-2006' Size: 994 Blocks: 8 IO Block: 4096 regular file Device: 306h/774d Inode: 26045738 Links: 1 Access: (0600/-rw-------) Uid: ( 1000/ kronos) Gid: ( 100/ users) Access: 2006-02-05 18:42:52.185598250 +0100 Modify: 2006-02-05 18:42:53.189661000 +0100 Change: 2006-02-05 18:42:53.189661000 +0100 Mutt opened: kronos:~/Mail/Lists$ stat ML-testml-February-2006 File: `ML-testml-February-2006' Size: 994 Blocks: 8 IO Block: 4096 regular file Device: 306h/774d Inode: 26045738 Links: 1 Access: (0600/-rw-------) Uid: ( 1000/ kronos) Gid: ( 100/ users) Access: 2006-02-05 18:43:05.338420250 +0100 Modify: 2006-02-05 18:42:53.000000000 +0100 Change: 2006-02-05 18:43:05.338420250 +0100 New mail: kronos:~/Mail/Lists$ stat ML-testml-February-2006 File: `ML-testml-February-2006' Size: 1940 Blocks: 8 IO Block: 4096 regular file Device: 306h/774d Inode: 26045738 Links: 1 Access: (0600/-rw-------) Uid: ( 1000/ kronos) Gid: ( 100/ users) Access: 2006-02-05 18:43:05.338420250 +0100 Modify: 2006-02-05 18:43:31.960084000 +0100 Change: 2006-02-05 18:43:31.960084000 +0100 Mutt opened: kronos:~/Mail/Lists$ stat ML-testml-February-2006 File: `ML-testml-February-2006' Size: 1940 Blocks: 8 IO Block: 4096 regular file Device: 306h/774d Inode: 26045738 Links: 1 Access: (0600/-rw-------) Uid: ( 1000/ kronos) Gid: ( 100/ users) Access: 2006-02-05 18:43:59.073778500 +0100 Modify: 2006-02-05 18:43:31.000000000 +0100 Change: 2006-02-05 18:43:59.073778500 +0100 * With kernel 2.6.15 Before: kronos:~/Mail/Lists$ stat ML-testml-February-2006 File: `ML-testml-February-2006' Size: 0 Blocks: 0 IO Block: 4096 regular empty file Device: 306h/774d Inode: 26045738 Links: 1 Access: (0600/-rw-------) Uid: ( 1000/ kronos) Gid: ( 100/ users) Access: 2006-02-05 18:46:13.186160000 +0100 Modify: 2006-02-05 18:46:06.000000000 +0100 Change: 2006-02-05 18:46:13.198160750 +0100 New mail: kronos:~/Mail/Lists$ stat ML-testml-February-2006 File: `ML-testml-February-2006' Size: 1187 Blocks: 8 IO Block: 4096 regular file Device: 306h/774d Inode: 26045738 Links: 1 Access: (0600/-rw-------) Uid: ( 1000/ kronos) Gid: ( 100/ users) Access: 2006-02-05 18:46:13.186160000 +0100 Modify: 2006-02-06 17:38:24.547425000 +0100 Change: 2006-02-06 17:38:24.547425000 +0100 Mutt opened: kronos:~/Mail/Lists$ stat ML-testml-February-2006 File: `ML-testml-February-2006' Size: 1187 Blocks: 8 IO Block: 4096 regular file Device: 306h/774d Inode: 26045738 Links: 1 Access: (0600/-rw-------) Uid: ( 1000/ kronos) Gid: ( 100/ users) Access: 2006-02-05 18:46:13.000000000 +0100 Modify: 2006-02-06 17:38:24.000000000 +0100 Change: 2006-02-06 17:38:36.856194250 +0100 Note that with 2.6.15 the atime of the mbox is unchanged after opening mutt, while with 2.6.16-rc2 it does change (I guess that's what confuses mutt).
