Courier does read the complete maildir folder any time you access it. This design decision has been made on purpose and will likely not change. Mr. Sam told me so in an interview I made a year or so ago. Dovecot on the other hand indexes maildir mailboxes when you access the mailbox and, when using the Dovecot LDA deliver, updates the index whenever it add new mails to the mailbox. The difference is: Courier uses a lot more ressources that Dovecot. Ralf and I had the amazing experience that load on a machine dropped from 60 (!) down to 2 when we exchanged Courier POP for Dovecot POP. This alone is a reason to use Dovecot unless you have a good reason to waste ressources (and wait longer ...). See <http://postfix.state-of-mind.de/results/> for a comparison of IMAP servers and how they scale (on regular Intel hardware using RAID 5 and SATA discs): System Konfiguration Postfix 2.2.10 Fujitsu-Siemens S150 T3 Intel(R) Pentium(R) 4 CPU 3.60GHz 3GB RAM store: 3 x 1 RAID-5 > just using the SASL portion of dovecot?

It is also under steady development. Timo does a real good job on his server. p...@rick -- The Book of Postfix <http://www.postfix-book.com> saslfinger (debugging SMTP AUTH): <http://postfix.state-of-mind.de/patrick.koetter/saslfinger/>
