[Dovecot] Thanks! Migration UWimap -> Dovecot report

[Leroy van Logchem]

Best Dovecot devs,

We moved from UW-imap&pop3 to Dovecot this morning (~500 accounts) and
reduced our traffic from the home directory server to the imap server 
bigtime:

| 22 Nov|    0.1     0.8|    0.0     0.0|    0.4     0.5| 1550.6    
42.9| 1557.3    67.9|
| 23 Nov|    0.3     1.0|    0.0     0.1|    0.4     0.6| 1331.8    
37.3| 1337.2    46.3|
| 24 Nov|    0.0     0.4|    0.0     0.0|    0.2     0.2|  186.8     
8.8|  188.9     9.2|

Yesterday and the day before we averaged 1.35 TB of NFS traffic for all
the remote imap folders (mbox format) while today we only use 1/10th :)

Also the lazy purge and writes are absolutly fast now, thanks!

One question: Our pop3 users recieved all  mail while 'leave mail on 
server'
was enabled -it didnt delete it-. After one such run it's fine. Any idea to
improve a uw/ipop3d migration for the next time?

<dovecot.conf of rc15>
pop3_uidl_format = %08Xu%08Xv
pop3_client_workarounds = outlook-no-nuls oe-ns-eoh
