Hi,
I've been testing SIS over the weekend as it seems to be a nifty feature. I don't have that many users and mailboxes but still... I only added the following line to my configuration:
mail_attachment_dir = /var/spool/vmail/attachments
As a test I sent a mail from GMail to 2 mailboxes (1 To and 1 CC). The attachment got saved to the attachment directory (on ZFS):
# find . ./04 ./04/78 ./04/78/0478b28c2a4c235370bb3cef4bc0482bb6000dae-b8819638a60e574d5b530100bde47b1f-2088e7301f9e3c4dc97e0000bde47b1f-244 ./04/78/0478b28c2a4c235370bb3cef4bc0482bb6000dae-007dcd01a70e574d5c530100bde47b1f-98d08416e4712b4d75310100bde47b1f-192
# ls -l total 519 -rw------- 1 vmail vmail 242866 Feb 12 23:50 0478b28c2a4c235370bb3cef4bc0482bb6000dae-007dcd01a70e574d5c530100bde47b1f-98d08416e4712b4d75310100bde47b1f-192 -rw------- 1 vmail vmail 242866 Feb 12 23:50 0478b28c2a4c235370bb3cef4bc0482bb6000dae-b8819638a60e574d5b530100bde47b1f-2088e7301f9e3c4dc97e0000bde47b1f-244
So these files are not hardlinks, they are 2 seperate files. Checksums are the same:
# sum * 58522 238 0478b28c2a4c235370bb3cef4bc0482bb6000dae-007dcd01a70e574d5c530100bde47b1f-98d08416e4712b4d75310100bde47b1f-192 58522 238 0478b28c2a4c235370bb3cef4bc0482bb6000dae-b8819638a60e574d5b530100bde47b1f-2088e7301f9e3c4dc97e0000bde47b1f-244
# md5 * MD5 (0478b28c2a4c235370bb3cef4bc0482bb6000dae-007dcd01a70e574d5c530100bde47b1f-98d08416e4712b4d75310100bde47b1f-192) = 684863b31dad701857642caedcdbf20a MD5 (0478b28c2a4c235370bb3cef4bc0482bb6000dae-b8819638a60e574d5b530100bde47b1f-2088e7301f9e3c4dc97e0000bde47b1f-244) = 684863b31dad701857642caedcdbf20a
Did I miss something? I would have expected the file once in the attachment_dir.
