[Dovecot] Thanks! Migration UWimap -> Dovecot report
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 -- Leroy
