[Dovecot] Config review (2.0.5)

7 Oct 2010


      Since I have these performance problems after migration to 2.0.5 I'm
publishing my config for review. Can anybody spot any obvious signs of
trouble?
2.0.5: /usr/local/etc/dovecot.conf
OS: Linux 2.6.32-24-generic-pae i686 Debian squeeze/sid
auth_debug = yes
auth_debug_passwords = yes
auth_mechanisms = plain login
disable_plaintext_auth = no
auth_master_user_separator = *
mail_location = maildir:~/Maildir
wegen webmail!
mail_max_userip_connections = 1024
managesieve_notify_capability = mailto
managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date
Namespace für courier-compatibilitaet
namespace {
inbox = yes
location =
prefix = INBOX.
separator = .
type = private
}
fuer user*masteruser logins
passdb {
args = /usr/dovecot-2/etc/dovecot/dovecot.masteruser
driver = passwd-file
master = yes
pass = yes
}
Authorisierung via PAM, /etc/pam.d/dovecot
auth_cache_size = 64 M
passdb {
args = cache_key=%u
driver = pam
}
User via passwd
userdb {
driver = passwd
}
plugin Konfiguration
plugin {
mailboxen anlegen und subscriben
autocreate = Trash
autocreate2 = spam
autocreate3 = Sent
autocreate4 = Drafts
autosubscribe = Trash
autosubscribe2 = spam
autosubscribe3 = Sent
autosubscribe4 = Drafts
FullTextSearch
fts = squat
Quota
quota = maildir
quota_rule = INBOX.Trash:storage=+2048M
quota_warning  = storage=99%% quota-warning 99 %u
quota_warning2 = storage=95%% quota-warning 95 %u
quota_warning3 = storage=90%% quota-warning 90 %u
quota_warning4 = storage=85%% quota-warning 85 %u
Sieve
sieve = ~/.dovecot.sieve
sieve_dir = ~/sieve
Trash (wenn Mailbox voll, dann Trash und spam leeren)
trash = /usr/dovecot-2/etc/dovecot/dovecot-trash.conf
}
Wir sprechen alles
protocols = imap sieve pop3
unix domain socket fuer Postfix
service auth {
unix_listener /var/spool/postfix/private/auth {
group = postfix
mode = 0660
user = postfix
}
user = root
}
imap-login Prozess
high performance mode
service imap-login {
service_count = 0
}
der eigentliche IMAPD
service imap {
drop_priv_before_exec = yes
process_limit = 2048
}
managesieve-login, wird nur genutzt von webmail aus
service managesieve-login {
service_count = 0
inet_listener sieve_deprecated {
port = 2000
}
}
der eigentliche managesieve
service managesieve {
drop_priv_before_exec = yes
process_limit = 128
}
pop3-login Prozess
high performance mode
service pop3-login {
service_count = 0
kein pop3, nur pop3s!
inet_listener pop3 {
port = 0
}
}
der eigentliche pop3
service pop3 {
drop_priv_before_exec = yes
process_limit = 512
}
die ganzen SSL Zertifikate
ssl_ca = </etc/ssl/certs/ca-certificates.crt
ssl_cert = </etc/ssl/certs/cert-188235905-postamt.charite.de-g02.pem
ssl_key = </etc/ssl/private/postamt.key
schoene Ausgabe in ps auxwww
verbose_proctitle = yes
version_ignore = yes
mail_fsync = never
maildir_very_dirty_syncs = yes
globale settings, die anderen werden ja nach Protokoll individuell ergaenzt!
mail_plugins = notify mail_log
imap kann am meisten
protocol imap {
mail_plugins = $mail_plugins quota imap_quota trash fts fts_squat autocreate
}
pop3 hat workarounds
protocol pop3 {
pop3_client_workarounds = outlook-no-nuls oe-ns-eoh
pop3_lock_session = yes
pop3_uidl_format = %v-%u
}
LDA macht noch zusaetzlich sieve quota trash
protocol lda {
mail_plugins = $mail_plugins sieve quota trash
postmaster_address = postmaster@charite.de
quota_full_tempfail = yes
syslog_facility = local4
}
der schickt die Quota warnmails
service quota-warning {
executable = script /usr/local/scripts/quota-warning2
user = root
unix_listener quota-warning {
mode = 0666
user = vmail
group = users
}
}
