Hi,

What exactly do you mean with "deliver preps the index"? Dovecot itself preps/creates/alters the index, when retrieving mail; right? Or are you (probably) saying this is one more benefit of using 'deliver'.

Anyone know of any 'deliver'/(dovecot) stresstests with regards to forking and threading of the deliver binary?

Cheers,

Jan

robust. But this can be explained because Dovecot is build for _retrieving_ mail (imap/pop) and _not_ delivering mail.

Deliver preps the index, makes retrieving email faster. More so for the average disorganized INBOX in my only folder customers.

Sieve makes a lot of things smoother for users, the customer. Especially if they expect server side rules. Obviously the rules that drop each message into a Backups or forward messages to other hosts take up what they take up.

My sievec files have ancient mtimes. They are definitely not recompiled upon receiving each email.

Any thoughts on this? Are there people out there with large Dovecot+Sieve implementations (100k+ users). Are there benchmarks available; how well does it perform under heavy load (mails/sec)?

Depends entirely on the sieve rules in place.
