     Read the man page of xz(1) . With -9 compression level 674 MiB of 
ram are needed. If you use dovecot+xz, you really need to increse vsz_limit.

     Personally, I would not use xz (-9) for main storage in a busy 
site. If you get +20 messages/second you need a lot of ram only for 
compression. I would use xz (-9) for alternate storage, tough.
