[Dovecot] dovecot and time

[Rick Romero]

I found something interesting via strace.  lda is writing a timestamp  
with utime before doign the fsync, but I'm really not a C guy, so I  
have no idea why that's going on via procmail and not via commandline.  
  I assume it's related to the choice of pread64 vs read.

when called from commandline (working):

read(0, "July 14-20, 2013\n10 courses. Bon"..., 4096) = 4096
read(0, "s bigger\nthan most realistic cyb"..., 4096) = 4096
read(0, "olina company in\nnumerous small,"..., 4096) = 4096
read(0, "on't have any way to tell you\". "..., 4096) = 4096
read(0, "rer. This version of Chrome addr"..., 4096) = 4096

Should I attach full traces?  They're 32k and 64k respectively.  Sorry  
about the lack of threading, I had my subscription off and didn't get  
a copy to reply to :/
