HDD space may be cheap, but is also slow, therefor IOPS are very expensive. I compress the mail using zlib, because even a very slight compression rate as 3 reduces the IOPS by more than 50% in my measurements and in my environment. As long as you don't plan to use a Raspberry Pi as your Dovecot server, todays CPUs are easily able to cope. And, please anybody correct me if I am wrong, if you use imap_zlib then the IMAP connection is compressed as well which may allow Dovecot to skip the decompressing state completely and just deliver the compressed stream directly. (Althought I don't know anymore where I read this and may be totally wrong and bogus. Please confirm with anyone knowing the code. Thanks.) Also reducing the needed space is a welcome bonus for me.
