First of all i would like to thanks Timo for the excellent job done in dovecot.
We are using it in you prodution server with about 5 millions of emails and it is pretty good, only a performance problens but i guess it is realated to ocfs2 that we are using.
So lets begin:
We are using dovecot 2.0.6 with maildir in an ocfs2 partiton.
It is pretty slow access in peak time, but it is related to ocfs2 as i said before, i am trying to mimimize the ocfs2 latancy by using mdbox. Another problem that we have are Full backup that takes about 24h and incremental takes about 13h
I am thinking in converting some email for testing propose, but i am wondoring how would dovecot convert this, like if i convert all mail from maildir to mdbox it would make many mailbox based on this seetings ? Or in the first convert it would make a big mdbox file and after it it will rotate by day or it would make many boxes just based on size?
mdbox_rotate_size = 5m mdbox_rotate_interval = 1d
Well, another thing can i make rotate interval happens in a certain time of day? end from where it takes this time ? it rotates at midnight ?
Another one!, if i lose the index files what really happens ? Sometimes in my server the index get corrupet and as i am reading mdbox index files held information that is not in other place. So what should i do to prevent any possible lose of data even if i lose the indexes?
I was reading about backup restore also, but i did not get it pretty well. With maildir we simple restore the files and the index gets rebuilt! What should i do with mdbox ? Restore the files and the index ? But how about the other emails that the account got after the backup, how i should merge the multiple files and more importanet how do i merge the index files ?
Well, sorry about my english!
And Thanks alot guys!
