I temporarily enabled zlib and ran dsync with verbose output. I think I could've also just added -o mail_plugins=zlib but I didn't think of it until later. # dsync -v -u te...@dop.com -m MyMailbox -o plugin/zlib_save= backup maildir:/path/to/temp/folder dsync(te...@dop.com): Error: Cached message size smaller than expected (4236 < 8192) dsync(te...@dop.com): Error: Maildir filename has wrong S value, renamed the file from .../terry/.MyMailbox/cur/1386272980.M20857P20282.mailbox.dop.com,S=4236:2,S to .../terry/.MyMailbox/cur/1386272980.M20857P20282.mailbox.dop.com,S=4236:2,S dsync(te...@dop.com): Error: Corrupted index cache file .../terry/.MyMailbox/dovecot.index.cache: Broken physical size for mail UID 37695 These 3 lines are repeated again. Why does dsync rename the file to the same name? I was able to import the now uncompressed email back into dovecot: # doveadm -v import -u te...@dop.com maildir:/path/to/temp/folder "" mailbox MyMailbox SENTON 2013-12-05 doveadm(te...@dop.com): Error: Cached message size smaller than expected (4236 < 8192) doveadm(te...@dop.com): Error: Maildir filename has wrong S value, renamed the file from /path/to/temp/folder/.MyMailbox/cur/1386272980.M20857P20282.mailbox.dop.com,S=4236:2,S to /path/to/temp/folder/.MyMailbox/cur/1386272980.M20857P20282.mailbox.dop.com,S=10267:2,S doveadm(te...@dop.com): Error: Corrupted index cache file /path/to/temp/folder/.MyMailbox/dovecot.index.cache: Broken physical size for mail UID 37695 doveadm(te...@dop.com): Error: Cached message size smaller than expected (4236 < 10267) doveadm(te...@dop.com): Error: Corrupted index cache file /path/to/temp/folder/.MyMailbox/dovecot.index.cache: Broken physical size for mail UID 37695 Hopefully this might help someone who ends up in the same situation. -Terry Terry Barnum digital OutPost http://www.dop.com
