Dear Jeffery, Thank you for your question and hints. I have seen similar problem with mutt 1.5.20 since half an year ago. (And reported it the other day)
You said: "if I do anything that changes the inbox file, such as deleting a message, then the Gnome mail monitor sees this change and begins indicating that there is new mail". This is a good discovery. It looks that mutt 1.5.20 forgets to clear or set something which would avoid the mail monitor or mutt itself think there is new mail. (I've rewound my mutt back to 1.5.18, which runs perfectly.) Would you please check the file status of the mailbox with the 'stat' command? This is my test on mbox.mutt with mutt 1.5.18: (1) Before I leave the mail box 'mbox.mutt': ----[23:45:20] $ stat mbox.mutt File: `mbox.mutt' Size: 38403 Blocks: 80 IO Block: 4096 regular file Device: 805h/2053d Inode: 687405 Links: 1 Access: (0600/-rw-------) Uid: ( 500/ jie) Gid: ( 500/ jie) Access: 2010-08-08 23:45:10.000000000 +0800 Modify: 2010-08-08 23:35:02.000000000 +0800 Change: 2010-08-08 23:35:02.000000000 +0800 (2) After I left the 'mbox.mutt': ----[23:46:36] $ stat mbox.mutt File: `mbox.mutt' Size: 13651 Blocks: 32 IO Block: 4096 regular file Device: 805h/2053d Inode: 687405 Links: 1 Access: (0600/-rw-------) Uid: ( 500/ jie) Gid: ( 500/ jie) Access: 2010-08-08 23:45:10.000000000 +0800 Modify: 2010-08-08 23:35:02.000000000 +0800 Change: 2010-08-08 23:46:47.000000000 +0800 Note: The time of 'Change' is updated to newer than the time of 'Acesss'. (Because I deleted a message in it.) Please help check if your mutt 1.5.20 does the same thing or not. (You need to delete a message in it.) best regards, charlie On Sun, Aug 08, 2010 at 04:27:53AM +0000, Jeffery Small wrote: > I have been using mutt 1.4.2.1i for quite some time on my Solaris 10 system > with the Gnome desktop manager.
