we are running dbmail since summer 2009 on all mailservers with postfix and dovecot as imap/pop3-proxy in front for several reasons "some thousands of mails" are peanuts make sure you have neough RAM and a good innodb-configuration if you are starting now make sure you use dbmail3 and NOT the 3.0.0 - 3.0.1 was announced some days ago and i had some hard debug sessions with Paul (core-developer) to get rid of many problems in the 3.0 series http://git.dbmail.eu/paul/dbmail/log/ i just updated to this GIT-snapshot silenting some imap-warnings in thunderbird http://git.dbmail.eu/paul/dbmail/commit/?id=62c20e2b2c15909941916bfe3c71386b31acc82a ________________________ innodb-settings froma production server with some hundret users and currently 50.000 messages with totally 9 GB mailsize for these settings you need a machine with around 8 GB RAM and MySQL >= 5.5.8 innodb_buffer_pool_size = 3584M innodb_buffer_pool_instances = 4 innodb_purge_threads = 1 innodb_max_purge_lag = 200000 innodb_max_dirty_pages_pct = 60 innodb_additional_mem_pool_size = 64M innodb_log_file_size = 512M innodb_log_buffer_size = 256M innodb_thread_concurrency = 32 innodb_thread_sleep_delay = 10 innodb_flush_log_at_trx_commit = 2 innodb_support_xa = 1 innodb_lock_wait_timeout = 50 innodb_table_locks = 0 innodb_checksums = 1 innodb_file_format = barracuda innodb_file_per_table = 1 innodb_open_files = 600 innodb_io_capacity = 800 innodb_read_io_threads = 8 innodb_write_io_threads = 8 transaction-isolation = READ-COMMITTED
