Hello Timo,
I'm having a problem with mbox that opening folder is slow when new mails are delivered to a folder. I'm delivering through the deliver program. Deliver updates index files but IHMO not completely correct. Therefore I compared index files before and after: 1.) Just delivered 2.) After accessing through imap via Thunderbird
diff looks like (stripped down to the relevant things): INDEX: -first recent uid ......... = 25847 +first recent uid ......... = 25848 -log file tail offset ..... = 16468 -log file head offset ..... = 16468 +log file tail offset ..... = 16828 +log file head offset ..... = 16828
- sync_mtime . = 2012-08-30 19:38:05
- sync_mtime . = 2012-08-30 20:09:23
- dirty_flag . = 1
- dirty_flag . = 0
- highest_modseq = 11162
- highest_modseq = 11163
- log_offset ... = 16468
- log_offset ... = 16828 CACHE: -used_file_size ....... = 6385696 +used_file_size ....... = 6392132 RECORD: seq=25663, uid=25835, flags=0x00
- ext 0 keywords : (0000)
- ext 1 modseq : 11156 (942b000000000000)

- ext 3 cache : 0 (00000000)
- ext 3 cache : 6385696 (20706100)
- ext 4 header-md5: (00000000000000000000000000000000)
- cache offset=6385696 size=488, prev_offset = 0
- hdr.BCC:
- hdr.CC:
- hdr.CONTENT-TYPE: 18: Content-Type: text/plain; charset=us-ascii
- hdr.DATE: 13: Date: Thu, 30 Aug 2012 19:37:24 +0200 <some other hdr.xxxxx lines removed>
- size.virtual: 1081 (3904000000000000)
Same patterns from record: 25664-25675
What does dirty_flag=1 mean? Why are the cache headers missing and not written by deliver?
Any ideas?
Config is below.
Thank you.
Ciao, Gerhard
